The worst draft you write is still better than the brilliant one you only thought about.

An idea in your head has no flaws because it has no edges yet. The moment it exists on paper it becomes something you can cut, rearrange and fix, and something other people can react to. A bad version is workable material. A perfect version that was never written is just a feeling you had once.

Give yourself twenty minutes and produce the ugly first attempt: the essay, the message, the song, the application. Do not fix anything while you are making it. Tomorrow you will have something to improve instead of something to imagine.
