I have problems focusing long term. It's not just boring stuff - I even have problems trying to play a game for more than half an hour. If there is an external force compelling me to do so it helps - whether it be a project deadline, or a multiplayer game where just quitting would leave teammates screwed, etc. I've heard wonders about ADHD drugs, but I'm hesitant to pop a pill for something that is more of a big annoyance than critical. On a weird note, I've heard people swearing that taking an ADHD pill before a coding interview works wonders. Not that I am advocating this lightly. I know back in college there was a black market for ADHD pills where students use them while cramming for exams, etc.
