1. Spend time with family.
2. Read before bed. However, read something that has nothing to do with work.
3. Plan in order to relax the mind:
Create a list of what was accomplished in the prior day.
Note what was not accomplished, and what should be to dos for the day ahead.
Note new to dos for the day ahead.
4. Turn off the cellphone and other computing before bed (I think the TV too, I can never sleep with it on).
5. Get seven hours of sleep.
