This is all stuff that has been acknowledged by many for years, and echoes what I've said myself on my various radio shows, but it's still an interesting read:

Basically he's saying that you will go broke unless you live a frugal lifestyle while on the road playing poker, and that the media is shoving the "baller poker player" down everyone's throats, not showing the reality that most of those "ballers" go broke quickly.
The problem is the quality which makes many tournament players good (unpredictability / willingness to risk money) usually bleeds into their lifestyle.
It is extremely tough to be aggressive and seemingly not care about money at the poker table, and then live your life as a cheapskate who counts every dollar.
Not only can the big scores warp your mind, but even the buyin sizes can screw with your head. If you regularly play $10k or $25k events, it is hard to take any expenditure of $50, $100, or even $1000 seriously. So that's where the players go crazy with the room service, the expensive hotel rooms, the first class flights, the expensive clothes, the club bottle service, etc. You just picture each of these (individually) as less than 10% of a single buyin, and you can easily dismiss them in your head, not realizing how quickly it all adds up.
The bottom line is that you either have a respect for money, or you don't.
A strong respect for money will hurt your poker game a little bit, but will help you hold onto whatever you win.
A lacking respect for money will lead to you being broke very quickly.
