I'm just like that, but minus the expectation of release/money/success. To me, the building and programming itself is the reward, and I have no motivation or desire to release anything I work on--or any belief that it would/should make money for me. To me, the hours spent fine sanding down and polishing my code, always approaching but never achieving perfection, is its own reward.

I would say thats a different thing entirely, an amateur in the original sense of the word

Latin amator, French amateur, means lover.

In this sense, it means somebody who is doing something because he/she loves it, not as his/her profession. It is not a large semantic shift to infer that he/she is not as skilled.
