The first step to not sucking is believing you're great. Me personally, I know for a fact I am the world's greatest guitar player. It doesn't matter that the world disagrees. They are wrong. The second step to greatness follows naturally from the first: humility. They had Clapton on NPR and the interviewer compared him to Robert Johnson and Clapton almost aghast. He's great and he surely knows it but he also knows he's not God. Yngwie on the other hand... The third step to greatness? Practice. Add obsession, a strong sex drive (no joke, that energy can be diverted to creative pursuits) and a dash of genius, stir and add time. Recipe for a guitar god.
