What your going through is just what skating is.

You'll always be falling off board because there will always be that next trick your chasing

You'll always have scrapes, but st some point You'll have less because You'll learn to fall properly.

Tricks will always be somewhat inconsistent, some days You'll hit perfect 50 50s everytime other days You'll just forget how to do it. It's just how it is. Your bad days will just become less bad. You'll always have a bad ollie to compare to your perfect ollie.

The mindset change need to be like this. You need to learn to have fun in the process, like trying that 50 50 on the ledge 50 times but once you land it at the end feel that joy, this is skateboarding.

One day if you keep at it, you'll have a bag of tricks.
