For me it helps to play computer games after work/school which take me away from my real world problems and don't challenge me too much. Basically something that gives me a good feeling of no fear and maybe even success without doing much for it. That helped me a lot to fight this brain-STFU problem.

Good tv shows also work, because watching tv basically is no challenge but is able to transfer your thoughts from your problems to problems that aren't yours which is less stressful.
