you cannot grow if you do not make mistakes. This is, basically, an iron law.

the difference between an amateur and a professional is the professional has made the mistake enough times to know how to either avoid it or fix it.

I cannot stress this enough:

If you can find a way to make your mistakes in a relatively safe and controlled way, you are training yourself to be able perform similar actions correctly under stress, when there's real things on the line.

Failure teaches you that some part of your approach didn't work. Failure teaches you about your assumptions. Failure gives you information. Failure is data. But only if you build the habit of listening to it.

one of the most useful properties of failure, if you think about it really hard, is that you're performing a bisection search every time you do it. The solution isn't the combination of the things you just tried, not under these conditions.

this is why school, mentors, workshops, etc are all so valuable: they're a controlled environment to make mistakes. in addition to using this to be kind to yourself while learning, please try to keep it in mind with those around you as well, and try to give others spaces or mentorship to make those mistakes safely. especially with how often our current society punishes people for them.
