This is actually how it played out for me once I recognized it. I'm of the mindset now that I can jump in and do things. And I think you hit on one of the most important lessons that came out of it for me - the only thing stopping you is you.

With that said, some form of representation helped me greatly with it. It doesn't need to be an exact match, but for me it needed to be enough to make me break my assumptions and see whatever weird walls I had put up in my thinking.
