Ten...ways to keep a clear head

1. Eat and drink without entertainment
2. Walk around the block 
3. Write a silly little ditty in 10 minutes
4. Clear your 'work' area (for writing, cooking, working, relaxing...)
5. Take your earphones out when you're not listening to anything
6. Look at something for a minute
7. Irish designer guy's little games
8. Stop what you're doing and lie on the floor
   
9. Set a timer and get that thing done. Right now. 
10. Ask yourself: do I want that, or is it just habit?
