1. Set a Pomodoro timer (25 minutes).

2. Tell myself "just work on the project/problem for just five more minutes."

3. * Work and allow no interruptions *

4. Pomodoro timer rings.

5. "Wow. I didn't notice time passing."

Almost always, the satisfaction of surpassing the 5 minute goal is enough encouragement to continue for a good long while.

Personally, this works as well (if not better than) changing my work venue.
