I wish that I could know for sure the causes of your problem. Partly because I often do the same things.
I don’t know that this is exactly protective behavior. Sometimes, we quickly get the essence of a new endeavor and find that it, in itself, is not fulfilling. We learn from our experiments, and can carry the knowledge on to other projects.
Writing/blogging is probably a good way to go, as you can communicate things as you learn. You are a good writer and your title is provocative.
I look forward to seeing more.
