It's just habit development. Developing any new habit requires a lot of energy the first few days. So you have to will through it when it starts.

Thinking of what you could have done better is good. Ruminating is dangerous, a downwards spiral of anxiety and rumination.

I'd write down thoughts to blog. Most of the time I throw it away after writing it down, only rarely is it blogged. HN is an outlet for that. But once you write it down, it's settled, you can tell your brain to go to bed.

But you need some willpower. Meditation helps. A run helps too, physical focus is another form of meditation. Commuting was a form of meditation - can't drive without a lot of focus, which left my mind unable to ruminate too much.
