Crilohthis is going to sound really weird but once you absolutely eat shit on a feature its not that scary anymore
Idk about this I think it depends on the fall you took and how it happened. I fucked up my shoulder this year on a fluke injury. Just caught an edge on an easy flat down. I was definitely a little rattled when i started hitting rails again a few weeks later. I do agree though, that if you fall on a feature and don't get hurt, even if its a bad fall, you now have a feel for what it feels like on that rail, or off the jump or whatever, helping you get it right the next time.
Basically dude, you're gonna fall, it might hurt, it might not, but its fun as fuck and there's nothing better than stomping a trick you've struggled to learn.
