To be clear, a failure is something that doesn’t work, an initiative that flames out. Your best hope when you fail is that the event will teach you something at the same time.
A mistake is either a failure repeated – doing something again when you should have known better – or a misguided action (because of casualness, or ego, or selfishness) that hindsight will kindly remind you is better to avoid.
You need a lot more failures, I think.
Failures that don’t kill you make you stronger and teach you one more way that won’t work, while demonstrating some things that might.
Truly, the failures I have had were not so serious, although they have been numerous. The mistakes I have made though. They continue to add up.
Fail as often as you need, but try to avoid mistakes. Cool?
