Poker NL-2 my mind progressive (or 2 important things to know)

Hello all! Today I want share my thoughts and then get comments and real advices from you after reading this topic.
Earning 150$ bankroll on Poker Stars I decided to wait with the transition to NL-5. I made 100$ cash-out and for remaining 50$ I continued play cash NL-2.
My game session last 6 hours and I played 2,5k hands. It was the biggest plays what I ever make. I was extremely happy because it raised my cash for 20$ !!!
I wish to pay attention to just how much has changed the psychology of my game. With a $ 20 bankroll and playing eight tables at the same time I was afraid and play tight and that as a result brought me basically a loss, very rarely a profit of 1 or 2 dollars.
But now I began to play very aggressively trying to pressure rivals high-bets, and you know what? They often folded. I am talking about NL-2.
So, I am the biggest opponent of slow play. I did not use the slow play even with obviously the best combination. You know, you could earn more money in the long run, if you will bet all-in on the flop or turn with the nuts than trying to use slow play because the opponent will think that you just want to steal the bank.
I just want to say 2 thing:
1 - DID NOT use slow play
2 - BE more aggressive
