The world cannot respond to work that remains inside your head.

Everything that stays internal is invisible to the world, which means it cannot be tested, used, corrected, or valued. The most sophisticated version of a thing in your head has exactly the same external effect as no version at all. Only what leaves can produce a response.

Move one thing out this week, in whatever incomplete form it currently has. Feedback, opportunity, and improvement all require something external to attach to.
