I first picked up the guitar because it's easier to carry than a piano (it's the actual reason!!)
then, I have tried to be the Best guitarist in the world (from age 14 to 20) and everytime I heard a new technique, I tried to master it so I became fluent at it... After all those years, I have understood that I'd always find someone with a new technique, and I have stopped trying to reach that goal..
I now write songs and my goal is to keep on earning a living playing the guitar and teaching music... ain't life great??
