Room for error
Build slack for being wrong: position size, cash buffer, no leverage — how room for error keeps you in the game.
Forecasts are fragile. Businesses surprise. You will be wrong sometimes.
Room for error means your plan still survives when you are wrong.
What room for error looks like
- An emergency fund so equity isn’t emergency cash
- Position sizes that can’t ruin you if one idea fails
- Avoiding leverage / F&O “shortcuts” while learning
- Valuing businesses with a margin — not paying for perfection
What zero room looks like
- Salary → full amount into one tip stock
- Averaging down with money needed for rent
- Intraday leverage because “I’m sure this time”
Skill cannot save a plan with no slack. Ordinary behaviour with slack often beats clever forecasts with none.

Graham’s margin of safety is room for error in price.
Housel’s idea is room for error in life and sizing.
You want both before you call yourself disciplined.
Checklist
- If this idea goes to zero, does my money order still work?
- Am I using borrowed money or futures to “speed up” learning?
- Did I leave cash or diversification for surprises?
