WHAT DO YOU KNOW NOW THAT YOU DIDN'T KNOW IN YOUR '20s and '30s?
DONALD TRUMP, mogul and star of "The Celebrity Apprentice" returning to NBC February 19, shares his business advice.
"What I know now is that experience is a great thing. You learn so much through experience. It's about trial and error. Ultimately it becomes a trial.
"I've learned many things through doing 'The Celebrity Apprentice,' too. You really don't know who is going to be great or not great. Sometimes you're so amazed and sometimes you're disappointed in people. You see them and meet them and say, 'Oh wow. They will be fantastic.' They turn out to be a dud. Or they turn out to be superstars.
"I also know that the harder you work, the better you do. Never ever quit or give up."
