Half-ready and moving beats fully ready and still in the driveway.

Readiness is mostly assembled in motion. You cannot know what the fourth problem is until the first three have happened, so a plan built entirely in the driveway is always solving imaginary versions of real obstacles. Waiting for full preparation feels responsible and usually just means the plan gets more detailed while nothing gets more true.

Start with the smallest real version. Not the whole business, one sale. Not the album, one finished track. What the first attempt teaches you will rewrite the plan better than another month of thinking about it would.
