Procrastinate.
   That's my #1 key to focus.
   If you have a good "oh crap I'd better get this done NOW!"
   sense, then get all the other stuff done. Cut your toenails.
   Brush your hair. Clean out a garbage can. Stare into the mirror.

   Don't distract yourself too much, but let yourself get bored of
   procrastinating. [and don't do the highly addictive stuff like
   Internet / TV / music - stuff that can take you away for hours
   and hours - they're a Time Suck]

   Just little things.

   Then suddenly, you'll be like. "Ok. I guess I'll do it now."

   And it won't be so boring.
