Shaq, who made smart investments in Google and Apple, shares his 'very simple' investing style

Shaquille O'Neal's money advice to young people

When former NBA star Shaquille O'Neal chooses which companies to invest in, he follows one rule: "I'm going to invest in things that are going to change people's lives," he tells CNBC's Bob Pisani at BITG's Charity Day, adding, "my style is very simple."

He's not focused on crunching numbers: "I never say, 'If I invest in this, five years down the line, we could sell it for this.' Every time I've had that model, it's always been a failure."

His method has worked out so far.

Since retiring from his 19-year basketball career in 2011, O'Neal has seen just as much success off the court. He has invested in Google and Apple and has since accumulated an impressive portfolio. He has embarked on a number of business ventures, owning restaurants and fitness centers and opening night clubs, and most recently, he has become the style ambassador for JCPenney's "Big & Tall" business.

When it comes to managing his personal finances, O'Neal keeps things just as simple: He saves 75 percent of his earnings and lives off the other 25 percent.

It's what he wishes he'd done when he was younger and what he recommends any young person coming into money do. "I went through a lot of trials and tribulations, a lot of failures," says O'Neal, who blew through $1 million in an hour after signing his first professional contract.

Since, he has learned to save at least 50 percent of his earnings right away, "and it's been working for me," he tells Pisani.
