Are you playing STT or MTT? 2/3 out of 5 bubbles is not good enough for STTs unless you always get first. Either way, if you really want to play them, start keeping track of every buy-in and what you place. I used to think very highly of my STT skills, but after a week's logs, I found that I was getting ITM only a little more than half the time, and for the time invested, was making a pittance compared to what I usually do in ring games. Log everything you do, everything you win/lose. Find out what your strong games are and stick to them. At least until your BR is more hefty.
I really like ring games. The income is relatively steady, although we're talking about poker here.
Whatever you do, no matter how good you think you are, start at the lowest stakes you can play
until your log tells you that you have them beat, then it is okay to at least
try (not stay at) higher stakes. BRM is key to success.
As far as how I tripled, I don't have anything to do this summer besides work, so I've been spending 1-5 hours a day playing poker. Whenever there was a day I would make a huge profit I would use some of it to play a MTT and I won one or two.
The man is on PokerStars. Thus I thought you might be talking about it, and not other sites that have nothing to do with him.
