Interviewer: Do you wake up in the morning and say ‘I'm successful,’ or do you feel you’ve 'made it?’

Donald: I think the second you say 'I’ve made it,’ you’ve kinda failed. I hope I never make it. I hope I’ve never made it. I wake up in the morning and say, “I’ve gotta be better, I’ve gotta be better.” I don’t think I’ll ever be satisfied.
