A slight OT anecdotal - most of the best MtG players I personally knew are now stock brokers.
The game itself, meta-game and the entire ecosystem around it taught me a lot about value, perceived value, sales, psychology... I don't regret any of the thousands dollars spent on it more than a decade ago.
