❓ Why It Matters
Short-term noise often forces investors out before value is realized. Long-term discipline increases the odds that fundamentals, not emotions, drive outcomes.
🎯 How to Practice
Extend research and review horizon, reduce unnecessary turnover, and adjust only when intrinsic value, risk, or opportunity cost materially changes.
⚠️ Common Pitfalls
Calling it long term while never reviewing thesis
Overtrading and damaging compounding
Ignoring opportunity cost and alternatives
