If your blog fails, you’ll have at least gotten better at writing.
If your podcast fails, you’ll have at least gotten better at speaking.
If your YouTube channel fails, you’ll have at least gotten better at presenting yourself in front of a camera.
If your venture fails, you’ll have at least learned how complicated it is to launch a business or a nonprofit.
And what constitutes failure? You get to decide. It could be a failure to reach a certain amount of viewers in a certain amount of time, a failure to get the project “off the ground”, a failure to get your Kickstarter funded, a failure to reach a certain amount of Patreon subscribers.
Here’s one way to tell if you’ve failed: whether or not you’ve been enjoying doing the thing that you’ve decided to do.
If you fail at that, then by all means, you have my permission to quit.
