You are a bad player. Trust me on this.

Bad compared to who? what level? I quit playing golf because no matter how much I tried I stopped getting better (and it stopped being fun). I was shooting in the upper 80's, lower 90's for years and never could reach the next level. I never considered myself a good golfer, but I consistently beat the group of guys I played with. Someone, a pro or a club owner, once told me that 90% of the players out there never legitimately break 100. But they can't build courses fast enough for all of these bad golfers.
Most poker players will never reach the success of the guys you see on TV, but those guys probably represent the top 1% or less of all poker players. The fact that you read and participate in a forum such as this shows that you have the desire to improve and will probably be a successful player even if you never become a great player. I pissed away a lot of money (for me) making small deposits and losing it all in a night, a week, or a month playing full table ring games. I started reading books and forums before I deposited any more money. I switched to playing Sng's and I haven't had a losing month in six months. I don't consider myself a great, or even good, player. But I've found a niche in which I can be a successful player.
I'd still like to move up in buy-ins and learn to be successful in higher limits, ring games, and games other than hold'em. For now I'm happy playing in, and making money in SnG's until I can afford to take those jumps.
Set long term goals. Play within your means (bankroll). Have fun.
