From time to time, I receive messages / questions like this: “Though it's interesting to know the shortcomings ( biases / behavioral finance) we may be facing, it doesn't really help noobs, or maybe even more seasoned investors, on what to do to avoid them. Does anyone have anything to share to expand on the things to do to become more disciplined, define exit strategy, things like that?” It’s a fair question. In fact, it’s probably one of the most honest questions an investor can ask. Because understanding behavioural finance is one thing. Applying it in real life, when markets are moving, headlines are loud, and your portfolio is flashing red or green , that’s a completely different game. And here’s the uncomfortable truth. There isn’t a clean, step-by-step formula you can follow and suddenly become “disciplined”. If there were, everyone would be doing it already. Behavioural finance doesn’t sit neatly in a spreadsheet. You can’t model it like earnings growth or discount cash flows....
