Before Van Gogh was Van Gogh, he painted some pictures of streets in Ramsgate, a village in the UK.
What if he had stopped, saying:
“This is not good enough, it is a failure, I’m never going to amount to anything?”
Nobody, ever once, pops to the top. You walk there. Step by step, each a failure until it’s not.
If you are not yet at Ramsgate, you have got some walking to do. And then, when you get to Ramsgate, more walking.
