I'm not focusing on the negative, I'm being realistic. The money list is showing the gross profit, not the net.
If I want to play in the US Open 9ball, it will cost $500/entry. About $500/week in hotel. $350 to fly. That's $1350 just to play, never mind eating out every meal for an entire week. You gotta get 9-12th in that tournament to break even after taxes. Also, this is one of the largest tournaments in the US so it's pretty much the best case scenario. International events, forget about it. Your nut just doubled or tripled.
So go through that top 25 list and keep all that in mind and you might start to see that those numbers aren't reality.
It's a business, you have to run yourself like a business. Keep expenses inline with your income. It's doable but most people playing "for a living" don't know anything but playing pool, just saying.
