I am only distracted when I have no problems. Show me a good problem or show me money, and nothing can pry me away from work.

I am a heavy chain smoker, averaging 30 cigarettes a day .. except when I am in hack mode. I can go for up to 10 hours without even noticing I haven't had smoke all day.

The other thing that motivates me is phone work and emails; when I have a contract or a deal in my sights I am in predator mode :-)
