"If I had to put the recipe for genius into one sentence, that might be it: to have a disinterested obsession with something that matters."

Pauls words sound great, but when you break them down, there is so much couching in generalities, its hard to grok at a deeper understanding. It's the 'smart person trying to sound smart' pitfall we all seem to fall to, no matter how humble our intentions.
