## Common Pitfalls

| Pitfall | Problem | Fix |
|---|---|---|
| Journaling without reviewing | Data collected but no learning | Weekly review is mandatory |
| Vague journal entries | Cannot extract patterns | Be specific: exact emotional state, exact rule broken |
| All focus on strategy | Psychology ignored | 80% of edge comes from execution, not system |
| Perfectionism | Beat yourself up over every loss | Losses are data, not failures |
| Comparing to others | Envy leads to size-up and FOMO | Your only competition is last week's you |
| No off switch | Trading identity consumes everything | Scheduled off time is performance enhancer |
| Ignoring physical health | Tired brain makes poor decisions | Sleep and exercise are trading tools |

## Best Practices

- **Journal every trade** — self-awareness is the foundation of improvement
- **Process over outcome** — did you follow the rules? That is success
- **Reduce size when off** — fighting mental state is expensive
- **Take breaks** — trading fatigue is real and costly
- **Weekly review non-negotiable** — the feedback loop drives growth
- **One change at a time** — fix one psychological pattern per month
- **Physical health first** — sleep and exercise are your highest-leverage tools
