How do you stay focused?
I’m not sure that I do. I’m kind of all over the place, with my attention split between web apps, iOS games and apps, and Safari extensions. I’m not especially disciplined. I use plain old text files for todo lists. I try to limit my time on Twitter and in my inbox. If I feel my focus waning, I let it wane. Curiosity or that unpleasant feeling of leaving something unfinished usually draws me back to a problem or task before too long.
