As long as there is something new to learn, it's easier to deal with for me.
Like, I might never kickflip a 7-stair again and it might be kind of sad, but I'm also finally learning back tails on a curb.
If you're talking strictly flatground, that's what I mostly skate now and yes I do feel that. One sesh I took an hour to land halfcab heel. Next time, 2nd try. It's so random. Just focus on new shit if you're bummed on old shit.
