If you write something and put it out there today, you may be doing your future self a favor. You are guaranteeing that, two years from now, you will have a body of work to look at. That’s worth something.
If you don’t write something and put it out there today, you are guaranteeing that you won’t get a phone call from a complete stranger two years from now telling you how the thing you wrote had an impact on them and their work.
The long tail. Drip. Drip. Drip. And all the rest of it.
What are you waiting for?
