I used to think that meant something like: “Create something that will sell. Create a product. Create something snappy. Also, you have to promote it on Twitter.”
Now I think I know what it really means. It’s much simpler this way. It means: “Create something that will make you proud.” That’s it.
Forget a product. Forget sales. You need only create something that is entirely your own. It does not have to be compact or marketable. It just has to be visible.
