Well you got lucky and went on a winning streak early on in your poker life. You will have bankroll swings good and bad simply part of the game. Your upswing was a VERY good one not a normal occurance. That is why you can't duplicate the results unless you find equally bad players and get equally good cards you likely won't duplicate it for quite some time. The key is to max your wins and minimize your loses thats all you can do... Congrats though good to see you will continue playing
