Although "Shark Tank" star Kevin O'Leary says he doesn't like to "peg a number" to certain financial milestones, he does believe there is a point in one's life where they should have at least six figures saved.

"By the time you hit 33 years old, you should have $100,000 saved somewhere. Make that your goal. Thirty-three [and] $100,000," O'Leary tells CNBC Make It.
