I had read that article before. It's not something that I would consider a problem for myself...I rarely if ever abandon a project in the middle, and when I do, it's a) always been a personal project or goal that affects no one else, and b) always been something that turned out to be either a bad idea in the first place (i.e. my goal at age 14 of weighing 110 pounds...would never happen unless I actually develop an eating disorder), or important to me for the wrong reasons (going to the Olympics for swimming). Etc.

Note that this isn't any kind of argument against your point... If anything, it's my own personal failure mode of assuming everyone's brain is like mine and that their main problems are like mine.

However, I think it does count for something that nyan_sandwich posted this article, noticing a flaw in his reasoning, on LW...and got upvotes and praise.
