Irving is going to eventually regret the opportunity he wasted. He's too young now. But when he gets around 40, and he can't move around like he used to and he's working a $30,000 a year job, and he's about to be kicked to the side by some 20 something who will work for half he makes, his blown opportunity will smack him in the face as hard as Mike Tyson punch.
It's so sad that a habit can seize control of a man and won't let him go until it has exacted all it can.
Sin will take you further than you want to go, keep you longer than you want to stay, cost you more than you want to pay.
