Write the book, paint the thing, record the song. Your work can hang around long after you do.

Made things have a life of their own once they exist. A song or a page does not need you present to do its work, and it can reach people who never met you. That is a strange kind of reach, and the only requirement is that the thing actually gets finished rather than described.

Pick the one you keep talking about and give it a real slot this week. Not the whole project, just the first rough version of a small part. Finished and imperfect outlasts perfect and imagined every time.
