Week 31 Day 7: Your Crash Journal: Write It Now, Read It Then

During a crash, you will forget everything you learned about staying the course. Your emotions will scream 'sell everything!' A letter from your calm, rational self is the best defense against your scared, emotional self. Write it today.

Template for your crash letter: 'Dear Future Me, I am writing this on [date], when markets are [calm/rising/normal]. My portfolio is currently worth $[X]. I know that at some point, it will fall 20-40%. When that happens, I will want to sell everything and hide in cash. Here is why I will not: (1) I do not need this money for [X] years. Temporary drops are irrelevant. (2) Every crash in history has been followed by a full recovery and new highs. (3) My automatic investments are buying shares at a discount during the crash. These cheap shares will compound for decades. (4) The people screaming on TV and Twitter do not know more than the 100+ years of data I have studied. (5) Selling locks in losses and turns temporary pain into permanent damage. My plan: continue my automatic $[X]/month investments. Rebalance once when stocks fall below [X]% of my target allocation. Do NOT sell. Check my portfolio no more than once per month. Turn off financial news. Remember: the purpose of this letter is that I wrote it when I was thinking clearly. If I am reading it during a crash, I am NOT thinking clearly. Trust the version of me who wrote this. Signed, [Your Name].' Keep this letter accessible. Review it quarterly. Add to it as you learn more.

The 'crash journal' is an implementation of the Ulysses contract (Elster, 1979) -- a binding pre-commitment made by a rational agent to constrain the future irrational agent. In Ulysses' case, he bound himself to the mast to resist the Sirens' song. In the investor's case, the letter serves as the mast, and the market crash is the Siren. Research on implementation intentions (Gollwitzer, 1999) shows that specific if-then plans ('If the market drops 25%, then I will rebalance and continue my contributions') are approximately 2-3x more effective at producing follow-through than general intentions ('I will stay invested during crashes'). The written letter forces the creation of specific implementation intentions. Rogers, Milkman, John, and Norton (2015) showed that concrete commitment devices (written plans, shared commitments, signed contracts) significantly increase adherence to beneficial behaviors, particularly when the behavior requires resisting strong emotional impulses. The crash journal combines multiple behavioral tools: (1) pre-commitment (writing the plan before the crisis), (2) implementation intentions (specific behaviors for specific scenarios), (3) narrative identity (framing 'staying invested' as consistent with your identity as a rational investor), and (4) temporal framing (the letter from your past self reframes the current crisis in the context of your long-term plan). This is not a substitute for a proper investment policy statement (IPS), but it serves as an emotional complement: the IPS addresses the analytical framework, while the crash letter addresses the emotional experience.
