Sometimes I write a list of things in the smallest detail. Then I cross off what I've done and it feels good. For example, instead of clean a room I will list each thing in that room that I want to accomplish:
Get up from computer
Take off slippers
Take shower
Put on really comfy clothes
Eat something
Clean of table
Dust table
Pick up socks
Put "X" away
Put "Y" away

Can even write in a break:
Make cup of coffee. Speaking of coffee, sometimes I will rely on a strong cup of coffee to get me going. (Other days I can't tolerate the caffeine)

Music. If it makes you want to move, or lifts your spirits, put some on to listen to, to move to.
