I've never felt rewarded for self-reflection, and I feel like every artist that emphasizes self-reflection never gains anything from it either.  Whether that's because they don't learn from it or because they feel the need to overanalyze themselves because they think its what makes them important.
it sounds like you are getting close to finding the right amount that people should think. you've figured out that 'too much' is too much. you are certainly onto something there
