Beat: My gameplan suxorz

[UsuallyDonating]

Im a pretty low stakes player (usually around $150 in my account). Like a moron i quit playing ring games all together to focus on tourneys about a year ago. I used to play .05/.10NL not to make money, but more for entertainment value. I did pretty well as far as that game goes. Since turning my attention to tourneys, my bankroll has been a rollercoaster. Ive had my bankroll over $1500 and a few day later its been under $100. Ive been playing SNG's and MTT's. Usually not playing anything over a $30 buyin when the roll is good and all $5 when its bad. Am i hanging myself figuratively by focusing on tourneys. Or do i just have poor bankroll management. Maybe im just a donkey who thinks he's half decent. Ive made alot of final tables and also went busto many times in the first hour. Any thoughts?
