I don't understand moving on when you get up 50% on a table. You mention so people don't get reads. It's better to stay at that table where YOU get reads and just mix up your game or take advantage of any reads you think they may get.

That seems like a very aggressive goal in a short period of time. $3000 in two weeks starting at below 25NL? I'm sure it's doable but don't get ahead of yourself or put too much pressure to meet that goal because it may affect your game. Just play good poker every time you play. I play 100NL and I would be ecstatic to win 3k in two weeks time.
