So true, and John IMHO is a guy who thinks out of the box, comes up with new ideas, and tries his hardest to bring them new ideas to market.
John is certainly very intelligent and he certainly thinks out side of the box and has come up with some incredible designs. But, with all that said he has little self control, and he doesn't know when to let Bull Shit slide off his back.
The funny thing is in most cases he doesn't even have anything to prove, his abilities and reputation speak for themselves. But John continues to try and prove that he is always right anyway even when he knows that he isn't. This in most cases in my opinion isn't really John trying to convince others as much as he is trying to convince himself what he is saying is true.
