Creativity loves a deadline you set for yourself and tell somebody about.

A private deadline is easy to move, because the only person who knows is the one who wants to move it. Saying the date out loud to someone changes the arithmetic: now there is a small cost to slipping, and that small cost is often all the structure a project needs. It is about making the commitment exist outside your own head, where you cannot quietly edit it.

Pick one thing and give it a date in the next two weeks. Tell one person who will actually ask you about it. Then do the smallest version that can honestly be called finished by then.
