10 to 500 in 2 days

I started playing poker online about 2 years ago on PokerRoom.com. Play money for awhile and then threw in 50 bucks. That didn't last very long as I decided that I was good enough and had the bankroll to play 2/4 limit hold'em. I have the bankroll now to play 2/4 hold'em, but still ain't good enough (i'm dead serious). I ended up dropping a few hundred and didn’t play there for about 1 year. This fall I threw in a few hundred to take advantage of a bonus. I withdrew what I earned after a month or so. A couple of days ago I got an email saying that they want my business back and have put a free $10 bucks in my account. I played a few SNGs over the last few days and got the account up to $30. I decided to “let it ride” and played a 5+rebuy today. I start the tourney very quietly. No good cards to be seen. I re-bought about 30 mins in to get my stack up to T2700. With about 15 mins left until the break I am still getting crap and decide to gamble with pocket 2s. I lose that race and am down around T800. I go into the tourney lobby to rebuy and notice that it is a 1rebuy +1add on tourney. So, I am sitting there damn near in last place waiting until the break so I can add on. I made it to the break, added on, and looked to double up. A little later I get 77 in the BB. A minimum raise is made and one caller. I decided to push. Both of them called another 1.5K in chips. Board read 10 high and I won the hand. I got lucky once not too long later when my AQ flopped a Q against AK. Don’t remember too many hands after that. I was able to get my stack up very quickly and was 1^st or 2^nd in chips when it was bubble time and had about 5x the chips of anyone at my table. I raised about 30% of the hands for 3-4 orbits and I didn’t get played with once. It really is amazing how passive people become just to be able to win back their buy-ins. I make it to the final table 5^th in chips. Survive some races and get down to 3 handed with 100K in chips with the other two having ~300K. Fortunately one of them was a total donk and he doubled me up and then called my all in with K6 (I held AK). Made a pretty shitty play HU. I had A2 suited, and called a raise. Flop came 2 7 10 rainbow. Called his bet w/ the hope that he would slow down and fold to my turn bet. Turn was 10s, giving me 2 pair and flush draw. I lead out/raised all in. He had K10 and it held. I think I should have raised his flop bet to see if he actually had something. By waiting to the turn I didn’t have necessary information and I was already committed to the pot.
