Kevin O'Leary says a $1,000 credit card is all you need to build credit
"Even though I don't endorse credit cards, it's very hard to advance your credit rating without having one"
"So it's good to get a credit card, put maybe a $1,000 limit on it, and then start paying it off. Use $200 a month and pay it off every month"
"I told my son, 'As soon as you get one, put $50 bucks on the card and pay it off.' Now he's got a pristine credit rating and he's only ever put a few thousand bucks through the card"
"Everybody should understand that there's no way to game that system. You've got to establish a credit rating or you can't borrow"
