I’ve been way too obsessed with stock trading lately. I made the right picks, but there were way too many times my nerve wasn’t there—I didn’t dare to go all-in. Not going all-in in itself is also a cognitive gap. This post is to commemorate my own self for not daring to take a heavy position. Fortunately, last month I went to Singapore to learn Texas hold’em from top-tier figures in the investment world, and I benefited a lot.
