do we get in our own way?

You need to finish your projects.
I want you to deeply internalize the benefits of finishing so much that it seems stupid not to push yourself through a project and see it through the completion.
Now as a disclaimer not every project needs to be or should be finished - sometimes circumstances change and there's no reason to keep working on

The refusal to acknowledge our creativity had its payoffs. We could wonder and worry about our arrogance instead of being humble enough to ask help to move through our fear. We could fantasize about art instead of doing the work. We could proceed to righteously ignore our creativity and never have to take the risks of fulfilling it.
