To be successful in anything, you have to have a passion for it, and that leads to being enthusiastic and demanding. I didn't have it for history. So I wouldn't have been a good teacher in that area. But I had it for basketball. And that's what coaching is at every level: it's about teaching.
My father and mother have given me so much love, so much support, that it would trivialize their parenthood if I would reduce it just to basketball. But my dad does call me before and after every game. And when we lost a game we shouldn't have, he told me it wasn't my fault. And I appreciated that, because he was trying to pick me up.
