I don't think that you can my friend. I have managed to rise to 2200+ but I still have tilt periods where I lose numerous games on the trot for a few days.
I think that you just have to accept that we all tilt from time to time and have confidence that it will come to an end soon. Even Fabi goes on tilt sometimes.
