Take a walk. Exercise will stimulate ideas because more oxygen will be pumped to your numb brain.
Have a good glass of wine and talk to a friend (or your pet) about something completely unrelated.
Read a book. Play a game (video games included).
Browse the Internet meaningfully.
Try something completely new and different (regularly): new route to work, new restaurants, new magazines, new habits, say hello to unknown people at work.
