This isn't fear of shipping, but fear of failure. Only way I know to overcome this is fail fast -> fail more -> learn -> fail less -> maybe succeed -> repeat.

This isn't fear of shipping, but fear of failure. Only way I know to overcome this is fail fast -> fail more -> learn -> fail less -> maybe succeed -> repeat. Somehow, you need to get comfortable with not knowing how it will all work and make sure you have given your best. Now best, would not mean the best product but something with the best fit. So it's not a step by step process here. The more and better you try, the more and better you understand the goal and how you may get there. Learn to be just ok with failing and have someone to get you back up on your feet.
