If someone doesn't buy your stuff, leave them alone.
If someone doesn't appreciate your work, walk away.
If someone doesn't get what you're doing, don't try to explain it.
People either get it or they don't.
And if they don't get it then all you can do is to walk away and focus on the people who get it.
Everything else is a waste of your time and resources.
Because people who don't get it don't want to get it.
And people who want to get it will get it...
