Not knowing isn't a problem. It's not doing. A failure in implementation, not information. You prepare, plan, intent, it never start delaying and excusing yourself is your mind's way of avoiding discomfort. It's not the task itself, but the emotions that may arise when you confront it. Feelings of rejection, fear of failure, or being judged. It's this fear of feelings that keeps you pinned in your comfort zone, which you are now realizing isn't all uncomfortable.
