I think missmisery's post hit the nail on the head.

Don't move up until you can beat the limit under it. Multi-table if you're just totally bored.

I don't reccommend 5-6 max, though...it's a different ball game.

Most of all, just play very tight, 20-25%, and bet those hands. Just play them straight up.

I became a winning player in less than a month, probably 90% (at first) of that could be attributed to hand selection. I just played pairs and big aces, and was very tight after a raise. You can easily turn a profit playing that way in lower stakes.
