One improvement I have learned from my childhood experience with my father: I do not threaten punishment in the morning. That was awful. Late into the night I would lie awake tossing and wondering what he was going to do to me. Usually he did nothing. A quiet, impressive 'talking to' was all I got.
It's important to run not on the fast track, but on your track. Pretend that you have only six months to live, and make three lists: the things you have to do, want to do, and neither have to do nor want to do. Then, for the rest of your life, forget everything on the third list.
