If the goal is attaining wealth then “wasting money” is probably a more accurate statement.
How someone decides to use their money is up to them. If emotional reinforcement helps them remember something then I suppose day trading is an option.
I’m only suggesting there are frugal ways to learn if your ultimate goal is to build wealth.
Regardless, there's a lot to be said for putting actual money down on your beliefs, it has a non-negligible impact on the learning process.
