Errr, I just went way off topic, didn't I?
Not that much. And I think what you said is - perhaps - related to what you imagine by "changing your life". Austerity is not the way, no more than abrupt modifications in your beeing (neither to reenforce your will by trying to control every thoughts and emotions btw. Control is the result, not the way).
