I'm not a fan of gambling by itself, but instead as a way of studying and learning about other things. For instance, I'm sure that if elderly people kept playing card games, it would help keep their minds alert. Studying poker involves studying human nature and probabilities. There are other aspects like studying risk in gambling, which is like studying risk in investing.
Does anyone have any examples of how gambling is like investing?
Gambling is only like investing if you are so good at a game that you make more than you lose. If you play poker with people you know and you almost always win because you can read the opponents, then that could be an investment.
