Tony Robbins didn't always have the cash to splurge. "I grew up dirt poor," he tells CNBC Make It. "We were always broke and trying to get by." And so, "early in my life, I thought, 'I'm going to make enough money that my family will never have to worry about this. I'm going to find a way to succeed.'" Robbins did just that: He has built a multimillion-dollar fortune as an entrepreneur, investor and business strategist. Along with his success, "I've had a few" significant, memorable splurges, he says. Perhaps his biggest one was when he was in his 20s and first started making big money. "I was about 24, 25 years old," he recalls. "I'd built a company that had become pretty successful and I had a really amazing economic month where I made half a million dollars in a month, which was incredible at the time. "And I always had wanted to go to Fiji. I always wanted to have an island but I couldn't afford it. And then I saw an opportunity at a place I loved" to invest in some property there, he says.

"I wanted to just try and buy one little condo at this place and they wouldn't do it, so I put the money in as a small investor in this resort and then my partners went upside down and it was the middle of a recession — I was really young, just getting my business going and it was a tough time during that time, but I wasn't willing to let it go. "I found a way, by hook or by crook, to figure out how to keep it together and make the payments." His doggedness paid off: "Today, I have about 525 acres and three miles of ocean frontage in the top resort in the country," Robbins says. The Namale Resort and Spa in Fiji, which he bought at age 29 for $12.5 million, is now valued at $52 million. He also splurged on a beach condo for his mom. "I'll never forget" the day he surprised her with the home, he says. "That moment of just shock at first … and then tears pouring down her face. "My mom's been gone now for more than a decade and it's still one of the most treasured moments of my life."

The greatest splurges are the ones where you splurge on the people you love because that has infinite value. Tony Robbins
