Why aren't we all Millionaires?

[chucklhead]

Howdy,
If your winning just 1 big bet per hour, and you use 300 big bets to determine your playing limit, you should be able to move up after every 300 hours of play. If you play 40 hours a week, you should move up about every 2 months. Why is it then that many players are still playing at the lower limits? Is it because they find a level that they can no longer make a profit at? As a professional, does the cost of living keep you from moving up? Are there not enough high limit games available on-line? I ask as my meager $30 on-line buy in has developed into a still meager, but more respectable by comparison, four digit bankroll. The recent discussion on bankroll requirements for playing multiple tables got me to thinking that I would rather play one 15-30 game that I could really concentrate on, than six 2-4 games.

Just wondering, currently I play for fun, so enjoy the game enough to sit and concentrate while not in the hand,
