I’m not really excited about celebrating failure, although events like FailFest are fun – and you can learn a ton from failure.
Failure is usually the default state. Sometimes, people go out of the way to find a way to fail. Celebrating failure is like celebrating the fact that it’s Thursday. If you want failure, change nothing, do nothing. Eventually whatever you are doing will fail. Nature is kind of built that way.
Success is much more interesting because it is both uncommon and rarely the result of doing nothing.
