Certain failure
Last night, a comedian tried out some new material, and someone in the front row didn't laugh.
Last week, I put up a post with a new idea in it, and thousands of people who read it didn't retweet or share it.
Last year, someone ran for office and didn't get every single vote cast.
Failure! Certain failure.
Of course your next project isn't going to delight everyone. That's impossible. It's certain that for some people, your project is going to be a failure.
At the same time, it's also quite unlikely that your project will please no one.
So now, we can agree that it's all on a spectrum, and that success and failure are merely localized generalizations.
Once you realize that failure is certain, it's a lot easier to focus on impact instead.
