This came from a question on a HackerNews thread.

So I used to have problems starting projects – I would plan/read/design etc and then never actually get around to doing anything concrete; I have overcome that issue. But now I find myself not being able to finish anything. I end up with little software projects that are half-done and abandoned because I lose motivation once I solve the ‘interesting’ challenges. When there is a clear path to the finish, I suddenly become disinterested.

This is something I still struggle with quite frequently. I’m not certain if it’s a particular chemistry in my brain or just a personality trait that I’ve developed over time. I find myself constantly hungering for interesting ideas and ways to solve problems. So much so, that the mental exercise of arriving at a unique solution has become a fun pasttime. This “not being able to finish” might seem like the main problem here, but I’d argue otherwise. Admittedly, the “problem solving” is hugely satisfying; more importantly than that, the problem that you’re trying to solve should be just as satisfying.
