I've been doing this ever since I read a blog by James Altucher. I just think of random ideas to stimulate creativity.
  1. Clean the house
  2. Work in the yard
  3. Take a nap
  4. Play a game
  5. Watch a movie
  6. Use the Headspace app to meditate
  7. Decide not to do some of the tasks on your plate
  8. Clean your office
  9. Organize your phone/computer
  10. Try to learn something new
