People that claim they build "for themselves" and yet enter contests are not being honest with themselves. By definition, a contest is a competition, where your model is displayed in a public setting, competing with other people's models, and being judged by others. If you enter a model in competition, you can no longer say that you only build "for yourself." No model was ever entered into competition that wasn't looked at, and judged, by others. Entering contests while claiming you only build "for yourself" doesn't pass the logic test.
