I'm not claiming it's a good or rational thing that I'm not motivated. (I'm also not claiming this happens to everyone with credentials.) I'm very nostalgic for that unembarrassed enthusiasm I once had, because, were I to possess it now, at least I would have a shot at producing something of value.

You may have gotten the wrong impression when I coupled this rueful sentiment with a criticism of the verbosity and redundancy of blogs and self-help books. These two things are in tension with each other but not strictly contradictory. "I am large, I contain multitudes."

I read that as a reference to Dunning-Kruger.
