Do you know what great motorcycle wheelies come down to? Bottom line?
It's about having a spine.
It's about having big, huge, hairy balls. No, not literally (because you probably shave them clean like a the porn star that you are (no offense to females or the LGBT community whom have various parts that may or may not need shaving/waxing/depilating)). You have to have done it enough, to have the confidence enough, to know that you're not going to throw that glorious machine, that weighs hundreds of pounds and will certainly crush that very spine, your very core, into smithereens, unrecoverably over the balance point if you get it wrong, even for a microsecond.
