To get over the initial "hump" with procrastination, there's one simple rule: JUST START.

Have you tried the Pomodoro technique? It's basically controlled time-boxing. I find that it helps me keep on track with whatever my current task is.

(Unless it's watching the progress bar for our automated system tests slowly creep across the screen, in which case I just go and check the empeg BBS).

Add Focus Booster. See how you get on.
