Would you fire your own mom to get ahead in life? Kevin O'Leary would. In fact, he says you should — if that's what it takes.

"You sacrifice everything, you do anything you possibly can — including firing your mother if you have to — to make that business survive," O'Leary said in an interview over a decade ago with"AfterShark" host Jason Cochran. And while the quote is from 14 years back, the philosophy hasn't aged a day.

"The only thing that matters in life is money," he continued. "Money is the blood of life and the blood of business. Without it, you're dead."

It's a harsh take, sure. But it's classic Mr. Wonderful — the name he earned for delivering harsh truths on "Shark Tank" and Canada's "Dragon's Den." And if you think he's exaggerating, you don't know O'Leary.

"If somebody says to you life is balance — it's just simply not true," he said. "If you're a real entrepreneur, there is no balance. You work on your business 24/7."

That kind of tunnel vision might sound extreme, but according to O'Leary, it's exactly what it takes to beat the odds. And the odds are brutal.

"Once you have success, once you have the personal freedom, you can pursue many other interests," he explained. "But until you get it done the first time, nothing else matters in the end."

It's not for everyone. Most people don't operate this way — and maybe that's the point.

Because to O'Leary, success doesn't wait for anyone. It demands everything.

And if you're not prepared to give it — even if it means cutting ties with the people you love — the money probably won't come.

Whether that makes him cold or clear-eyed depends on how badly you want to win.
