Sadly, the work is on my computer.
My ability to focus is directly linked to how comfortable I am where I am working, and how much there is to do.
If I'm at the library, or a coffee shop, I can work my ass off because there are people around me, and I don't want to be one of those guys sitting in a coffee house checking his Facebook.
If I'm at home... I'll do pretty much anything 'cept for work.
Or clean.
