Help with Blinds?

So last night I did not do so well as far as my winnings were concerned, but I stuck to my guns for the most part and played solid poker. I was down about 27% after 2 hours and I only tilted once after my set of 7's got beat by a set of 10's. But it was a brief tilt and gained only one hand that I though I did not tilt, I played very few hands and I thought I played well overall. Normally after 2 hours in a ring game I would be up or down 200-300% based mostly on how lucky I got with the cards.

I think I am making steps in the right direction but I am still having trouble with the blinds. I get committed too easily because of money I have already committed to the pot. I call the small blind with 1 gap connectors off suit and find myself staying in if it gets raised to see the flop. I need more discipline!

I played again tonight and started out crazy. I found myself playing crazy-loose but finally tightened up after I realized what I was doing. I got down about 35% before I caught myself and finally got back up to a 20% gain. I know Mike Caro would be having a fit about me trying to "manufacture a winning streak", but lets be real I am one in a row right now and 20% is nothing to write home about playing the stakes I am at. I just need a couple of winning nights to build my confidence...
