I'm considering it after reading this. I have considered it in the past, but you know... I find it hard to start and finish tasks once something else catches my fancy.

I don't know if it's me or modern culture but my brain needs instant feedback. Video games are nearly unparalleled for that. Programming is similar, exams and homework (unlike a lot of people posting here) do it for me too, because I get that feedback in a solid, concrete number.
