^^^ THIS!!! (for the most part)
It's all about receiving the right kind of advice and input from hotshoe dudes who've already paid the price to learn how to be fast.
Also... I don't care who in the bleep you are... you're going to have to learn how to walk a bike up a hill dismounted with the engine running and in gear and you using the clutch to make it climb up beside you in tough going. AND... you're going to have to learn how to turn around that bike on a steep uphill, with the engine killed.
