Replying to Teaching yourself tricks

Everything i have learned in skiing, i have taught myself. i suck at jumps and i can only do a 3 off of a medium ish jump. I can 2 off both ways and i can front 4 off with no need of a dropoff. Im trying to teach my friends how to do rails consistently, my one buddy learned in half a season and he can do urban down rails with ease. Is it ok to teach yourself everything? i sometimes ask for advice in the park. Anyone else teach themselves everything?
