Telling everyone your goal gives you the good feeling of finishing before you’ve started. Don’t cash that check early.

Announcing a plan delivers a small version of the reward immediately. People respond, you feel like someone who is doing the thing, and that feeling is satisfying enough to reduce the pressure that would have made you start. The goal has not moved, but the urgency has quietly drained out of it.

Keep the next one to yourself until there is something to show. If you need accountability, that is real, so tell one person who will actually check rather than an audience who will only applaud. Let the satisfaction stay locked behind the work, where it does its job.
