Both could certainly be correct, what the "smart" one's do, and what most do might be two different things...experience is what often makes one become "smart" along the way.
We've also seen quite a few "next big things" come and go in record time due to receptor burnout, and overdoing it early on....trust me, the one's doing th most amount of drugs either never make it, or aren't around too long. The veteren BBers that have had a steady and long career are indeed, the smart ones.
