I read somewhere a good starting point is if a task takes less than two minutes, just do it now. You start there and build. Never quite realized that's what I'd started doing on my own, but it has helped, especially after making it a conscious effort.

Now if someone could tell me how to deal with having a shift at work at the end of the day and the entire day before the shift being wasted because all I can focus on is that I have somewhere to be in 6 hours.
