Stock-Flow Diagrams for Life Decisions
Share
Life is about resourcesβmoney, energy, time, relationships, knowledge, health. These resources accumulate (stocks) and flow (in and out) over time. Understanding these dynamics is the key to making sustainable decisions. But most people think in snapshotsβ"How much money do I have now?"βnot in flowsβ"At what rate is my money increasing or decreasing?"
In Dynamic Divination Modeling Theory, we use Stock-Flow Diagrams (SFDs)βa systems dynamics tool that maps how resources accumulate and flow over time. Combined with divination, this creates a powerful framework for life planning, resource management, and long-term decision-making.
This article teaches you how to create Stock-Flow Diagrams from divination readings, transforming abstract guidance into concrete resource models you can use for strategic life planning.
What is a Stock-Flow Diagram?
Core Components
Stocks (Rectangles): Accumulated quantities that can be measured at any point in time
β’ Examples: Bank account balance, energy level, number of relationships, knowledge base
β’ Notation: Drawn as rectangles or boxes
β’ Behavior: Change only through inflows and outflows
Flows (Arrows with valves): Rates of changeβwhat moves into or out of stocks
β’ Examples: Income (inflow to money), expenses (outflow from money), learning (inflow to knowledge)
β’ Notation: Arrows with valve symbols (β³β²) showing rate control
β’ Behavior: Measured as amount per time unit ($/month, energy/day)
Sources and Sinks (Clouds): External reservoirs (infinite supply or capacity)
β’ Examples: The job market (source of income), the universe (source of opportunities)
β’ Notation: Cloud symbols
β’ Behavior: Don't deplete or fill up
The Fundamental Equation
Stock(t) = Stock(t-1) + Inflow - Outflow
This simple equation governs all stock-flow dynamics. Your bank account tomorrow equals your bank account today plus income minus expenses. Your energy tomorrow equals your energy today plus rest minus depletion.
Creating Stock-Flow Diagrams from Tarot
Step 1: Identify Stocks (What Accumulates)
Look for cards representing accumulated resources or states.
Pentacles = Material/Financial stocks:
β’ Four of Pentacles = Hoarded wealth (stock)
β’ Nine of Pentacles = Accumulated prosperity (stock)
β’ Ten of Pentacles = Generational wealth (stock)
Cups = Emotional/Relational stocks:
β’ Six of Cups = Accumulated memories (stock)
β’ Nine of Cups = Emotional satisfaction (stock)
β’ Ten of Cups = Family harmony (stock)
Swords = Mental/Knowledge stocks:
β’ King of Swords = Accumulated wisdom (stock)
β’ Eight of Swords = Accumulated limiting beliefs (stock)
Wands = Energy/Creative stocks:
β’ Nine of Wands = Accumulated resilience (stock)
β’ King of Wands = Accumulated creative power (stock)
Step 2: Identify Flows (What Moves)
Look for cards representing movement, action, or change.
Aces = Inflows (new energy entering):
β’ Ace of Pentacles = Money/opportunity flowing in
β’ Ace of Cups = Love/emotion flowing in
β’ Ace of Swords = Clarity/truth flowing in
β’ Ace of Wands = Inspiration/creativity flowing in
Fives = Outflows (energy leaving/loss):
β’ Five of Pentacles = Resources flowing out/loss
β’ Five of Cups = Emotional energy draining
β’ Five of Swords = Mental energy depleting through conflict
Knights = Active flows (rapid movement):
β’ Knight of Pentacles = Steady work flow
β’ Knight of Cups = Emotional pursuit
β’ Knight of Swords = Ideas rushing in/out
Step 3: Draw the Diagram
Create a visual map showing stocks (boxes) and flows (arrows).
Example: Financial Stock-Flow
[Income Source] β β³Income Flowβ² β [Bank Account] β β³Expense Flowβ² β [Sink]
Tarot mapping:
β’ Income Source = Ace of Pentacles (opportunity)
β’ Income Flow = Eight of Pentacles (steady work, $4000/month)
β’ Bank Account = Four of Pentacles (current balance: $10,000)
β’ Expense Flow = Two of Pentacles (balancing, $3500/month)
β’ Net flow = +$500/month (accumulating)
Step 4: Quantify Stocks and Flows
Assign numerical values based on card interpretation and reality.
Example quantification:
β’ Current stock (Bank Account): $10,000
β’ Inflow (Income): $4,000/month
β’ Outflow (Expenses): $3,500/month
β’ Net flow: +$500/month
β’ Projected stock in 6 months: $10,000 + (6 Γ $500) = $13,000
Complete Life System: Multi-Stock Model
The Four Core Life Stocks
Most life decisions involve four primary stocks:
1. Financial Stock (Money/Resources)
β’ Inflows: Income, investments, gifts
β’ Outflows: Expenses, taxes, losses
β’ Tarot: Pentacles suit
2. Energy Stock (Vitality/Health)
β’ Inflows: Rest, nutrition, exercise, joy
β’ Outflows: Work, stress, illness, burnout
β’ Tarot: Wands suit, The Sun, Four of Swords
3. Relational Stock (Social Capital)
β’ Inflows: New connections, deepening bonds, community building
β’ Outflows: Conflicts, distance, broken relationships
β’ Tarot: Cups suit, Three of Cups, Two of Cups
4. Knowledge Stock (Skills/Wisdom)
β’ Inflows: Learning, experience, mentorship
β’ Outflows: Forgetting, obsolescence
β’ Tarot: Swords suit, The Hermit, Hierophant
Integrated Stock-Flow Model
These stocks interactβflows from one stock can affect another.
Example interactions:
β’ Financial stock β Energy stock (money can buy rest, healthcare)
β’ Energy stock β Financial stock (energy enables work, which generates income)
β’ Relational stock β Financial stock (connections create opportunities)
β’ Knowledge stock β Financial stock (skills increase earning potential)
Case Study: Career Transition Stock-Flow Analysis
Question: "Should I quit my corporate job to start a business?"
Tarot reading (Stock-Flow Spread, 9 cards):
Financial Stock:
β’ Current: Four of Pentacles (hoarding, $50,000 saved)
β’ Inflow (corporate): Eight of Pentacles ($8,000/month salary)
β’ Outflow: Two of Pentacles ($5,000/month expenses)
β’ Net: +$3,000/month (accumulating)
Energy Stock:
β’ Current: Four of Swords (depleted, 3/10 energy)
β’ Inflow: The Sun (potential for renewal, if change happens)
β’ Outflow: Ten of Wands (burnout from current job, -2 energy/month)
β’ Net: -2 energy/month (depleting)
Knowledge Stock:
β’ Current: King of Pentacles (high expertise in current field)
β’ Inflow: Ace of Wands (new learning in business, +5 skills/month if start)
β’ Outflow: Minimal (skills don't deplete quickly)
Stock-Flow Diagram:
Scenario A: Stay in Corporate Job
[Salary Source] β β³$8K/monthβ² β [Financial Stock: $50K] β β³$5K/monthβ² β [Expenses]
Net financial flow: +$3K/month
[Burnout] β β³-2 energy/monthβ² β [Energy Stock: 3/10] β β³minimal inflowβ²
Net energy flow: -2/month (depleting toward 0)
Projection (12 months):
β’ Financial stock: $50K + (12 Γ $3K) = $86K (growing)
β’ Energy stock: 3 - (12 Γ 2) = -21 (burnout, unsustainable)
Scenario B: Start Business
[Business Revenue] β β³$0-4K/month (uncertain)β² β [Financial Stock: $50K] β β³$5K/monthβ² β [Expenses]
Net financial flow: -$5K to -$1K/month (depleting initially)
[Renewal] β β³+3 energy/monthβ² β [Energy Stock: 3/10] β β³lower stressβ²
Net energy flow: +3/month (recovering)
[Learning] β β³+5 skills/monthβ² β [Knowledge Stock] β (builds business capability)
Projection (12 months):
β’ Financial stock: $50K - (6 Γ $5K) + (6 Γ $2K) = $32K (depleting then stabilizing as revenue grows)
β’ Energy stock: 3 + (12 Γ 3) = 39 β capped at 10 (full recovery)
β’ Knowledge stock: Significant growth in business skills
Stock-Flow Analysis
Scenario A (Stay):
β’ Financial stock: Growing (+$36K/year)
β’ Energy stock: Depleting (burnout in ~18 months)
β’ Sustainability: Unsustainableβenergy stock will hit zero, forcing change anyway
Scenario B (Leave):
β’ Financial stock: Depleting initially (-$18K in 6 months), but $32K remaining is adequate runway
β’ Energy stock: Recovering (full recovery in ~3 months)
β’ Knowledge stock: Growing rapidly
β’ Sustainability: Sustainable if business revenue reaches $5K/month within 10 months (before financial stock depletes to critical level)
Critical thresholds:
β’ Financial: Need $20K minimum for safety (6 months runway at $5K/month burn)
β’ Energy: Currently at 3/10, need to recover to 7+/10 to sustain business effort
β’ Time: Have 10-month window before financial stock becomes critical
Decision: Leave corporate job. Energy stock depletion in Scenario A is unsustainable and will force change anyway (likely at worse time). Scenario B has adequate financial runway ($50K β $32K over 12 months) and enables energy recovery, which is necessary for business success. Key risk: Business must generate $5K/month revenue within 10 months.
Action plan:
β’ Month 1-3: Focus on energy recovery (rest, health) while building business foundation
β’ Month 4-6: Ramp up business effort (now have energy to sustain it)
β’ Month 7-10: Critical revenue generation periodβmust hit $5K/month by Month 10
β’ Monitor financial stock monthlyβif drops below $25K before Month 10, reassess
Advanced Technique: Delays in Stock-Flow Systems
Some flows have delaysβtime between cause and effect.
Example: Learning β Earning Delay
[Learning Effort] β β³+5 skills/monthβ² β [Knowledge Stock] β ||6-month delay|| β β³+$2K/monthβ² β [Income]
You invest in learning now, but the income increase happens 6 months later. This delay can cause:
β’ Impatience ("I'm learning but not earning yet")
β’ Premature quitting (giving up before delay period completes)
β’ Cash flow problems (expenses now, revenue later)
Divination insight: I Ching Hexagram 5 (Waiting) or tarot Hanged Man often indicate delays. Factor these into stock-flow projections.
Stock-Flow Optimization Strategies
Strategy 1: Increase Inflows
Find ways to increase the rate of positive flows.
Example: Ace of Wands (new opportunity) suggests potential to increase income inflow from $4K to $6K/month. This changes net flow from +$500 to +$2,500/monthβ5x faster accumulation.
Strategy 2: Decrease Outflows
Reduce the rate of negative flows.
Example: Two of Pentacles (balancing) suggests cutting expenses from $3,500 to $3,000/month. This changes net flow from +$500 to +$1,000/monthβ2x faster accumulation.
Strategy 3: Build Stock Buffers
Increase stock levels to handle variability.
Example: Four of Pentacles (hoarding) suggests building financial stock to $20K before taking risks. This provides buffer against unexpected outflows.
Strategy 4: Manage Delays
Account for time lags in planning.
Example: The Hanged Man (suspension) suggests 3-month delay between action and results. Don't expect immediate stock changesβplan for delay period.
Long-Term Planning with Stock-Flow Models
5-Year Projection
Use stock-flow equations to project long-term trajectories.
Example: Retirement planning
Current financial stock: $100K
Annual inflow (savings): $20K/year
Annual outflow (expenses): $0 (invested, not spent)
Investment return: 7%/year (additional inflow)
Year-by-year projection:
Year 1: $100K + $20K + ($100K Γ 0.07) = $127K
Year 2: $127K + $20K + ($127K Γ 0.07) = $155.9K
Year 3: $155.9K + $20K + ($155.9K Γ 0.07) = $186.8K
Year 5: $251.5K
Year 10: $476.3K
Divination insight: Ten of Pentacles (generational wealth) confirms this trajectory is aligned with long-term abundance.
Why Stock-Flow Diagrams Change Life Planning
Traditional planning: Static snapshots, "How much do I have now?"
Stock-flow planning: Dynamic models, "At what rate am I accumulating or depleting?" "What's my trajectory?" "When will I hit critical thresholds?"
This transforms life planning from guesswork into resource engineeringβyou see exactly how your resources flow and can optimize for sustainability.
The old way: Check bank balance, make decisions based on current state. The new way: Model stocks and flows, project trajectories, identify critical thresholds, optimize inflows and outflows, plan for delays, ensure sustainability. From static to dynamic. From snapshots to flows. From guessing to engineering. This is stock-flow modeling for life decisions.
When working with these systems, I find it deeply grounding to pair the analytical rigor with something that honors the intuitive side of the journey. The 40 Manifestation Rituals have become a quiet companion for me during transition periods, offering a structured yet soulful way to align intention with the flows I'm mapping. For those moments when the energy stock is running low, the Inner Sunlight Audio feels like a gentle reservoir of warmth I can draw from, much like the energy inflows we talk about in the models. And when I need to track the subtle shifts in my own knowledge stock and creative currents, the The 52-Week Tarot Journey offers a year-long rhythm to notice exactly where and how I'm accumulating wisdom.
