Robb, I enjoy your inspirational pep talks! Some of the differences I noticed when moving from 10NL to 25NL were:

-You can actually get people to fold some broadway cards with a 4-6x BB PFR. Good luck with that at 10NL.
-The check-minreraise on the flop seems to be the standard "tricky" play for that level on Stars. It usually means TPGK or better. At 50NL it's completely different and often means a draw, combo draw or a mid-pair on a dry board.
-There are a few decent short-stacking nits at 25NL, whereas at 10NL you really can't give any short-stackers credit for being good. Try to identify the good shorties and don't call their shoves without a very strong hand.
-People start paying attention to implied odds for chasing draws. At 10NL there are certain players that will chase them with their entire stack every time. At 25NL you need to pay more attention to sizing your bets so it would be a mistake for them to chase. Double-barreling a blank on the turn now becomes a useful play.

GL with your Op.
