I was hoping for that as well. Here's one trick at least for programmers: if you unit test everything right away, getting your pass rate from 0/100 to 100/100 can be like scoring in a game. Personally I've found this strategy feeds into all the habits I developed when I used to play computer games. Gamers have incredible focus; sitting in your chair for 10 hours straight trying to beat a level sound familiar? If you can leverage even a piece of that mindset I'd say you're in good shape in terms of focus.
