There's always a reason not to buy the bottom and always a reason not to sell the top. Some headline, some technical break, something that makes hesitation feel rational in the moment. That doubt tends to show up exactly when conviction is hardest to hold, not randomly. Bottoms feel like they can always go lower, tops feel like they can always go higher. That is how the psychology works in markets. It is good to be aware of this and check yourself from time to time. Also important to make plans while the market is boring. Because when things get crazy, in either direction, it will be harder to make rational decisions.
