Stats how to break through the glass wall?

After playing ~60+ Hours of FFXIII I finally got back into the sc2 beta at around the time where there where a lot of turbulence with random resets.

Which I actually kind of enjoyed since I did not feel the restraint I normally feel when I know my stats are going to last, it is such a release to play without the burden of stats dragging your morale to play down.
I have always struggled a lot with it both in the original Starcraft and in warcraft3 and well basically anything that would record and remember how I performed.
In Starcraft I would never play more then like 5-7 ladder games because when I got up to like 1150 I knew I would most likely lose and ruin my stats and in the original ladder get extremely punished for losing point wise.
In warcraft3 I where extremely hesitant to play ladder games as well due to the facts that at some point my win rate would start falling dramatically.
I realize it is completely silly and an absolutely useless attitude toward gaming especially if you want to improve your game, but it is there poking me at every turn and it is doing the complete opposite of 2 key factors for me.
1: encouraging me to play more games and therefore
2: improve my skill level.

I Wish I could just put this nonsense behind me and just play!, right now its only a beta I cant even begin to comprehend how I am going to feel when it goes live!

If anyone knows how to get past this I would really love to hear it!
