- Insight: Condensing key takeaways into short habits amplifies long-term behavior more than strict rules.
- David shares his two-page Things to Remember as a behavioral summary to help readers act consistently.
Add To Winners Not Falling Losers
- Do add to positions that are performing and showing durable business improvement rather than averaging down into falling businesses.
- David Gardner advises adding to stocks that look more like Rule Breakers and avoiding additions when competitive advantage or fundamentals are eroding.
