my father used to have a mental list of 7 items he tried to do every day. He said it helped keep him sane, balanced and human. the list is below:
1. do something mental
2. do something physical
3. do something spiritual
4. do something you have been putting off
5. do something you want to do.
6. do something for someone else
7. do something for yourself.

It seems to work for me.
