What I first did, was I would be standing still at the top of the stairset, have my one foot on my scooter, and hop on and kiss it, with one foot on my scooter. Then I would just go for it. I'm a lot better now, I hit an 8 stair rail two days ago first try, they're really easy you just gotta commit, get rid of that fear. Take a few runups, and go a little bit faster than you think you need to. But you gotta get on top of it. If you dont, your gonna eat shit. If you do, it's NEVER gonna be that bad. Once you actually go for it, ALL the fear goes away, it's wierd.
