Just for extra reassurance, I'll say the same as everyone else. It makes no difference - but if more people say it, it'll encourage you to keep trying. It IS just practice. Gotta find that balance point, and just get the knack of those little hops to recover balance. That's a good point actually. If you lift the front wheel up, and get to a point on the back wheel but start to tip over, hop the back wheel forwards/backwards/sideways according to which way you're falling. This'll correct your balance a bit, and - if you get it right - stop the front wheel from going down. Arms cocked, but not bent too much. Straight arms makes it SO much harder than it need be
