Had an interesting case study where a coworker liked to gamble - he was fairly responsible, kept to his budget and treated it like an expensive hobby he enjoyed- but at the same time, he had someone else handle his retirement investments, which is an unpredictable payoff market where you come out ahead on average. I asked a couple times why he didn't replace gambling with investing and never got a good answer. He was certainly smart enough that he could have had fun with the research and chance.
Then there was a market downturn and his investment advisor had to talk him down from selling in a panic, and I was like "oh... It's not an information problem at all. It's entirely an emotional regulation problem"
I should sell a "meditation for investors" course
