50 Cent is often considered to be one of hip-hop’s most well-off. He’s made millions outside of music—from signing a five-year endorsement deal with Reebok in 2003, to launching his own film and book companies throughout the 2000s, to partnering with Glaceau and making an estimated $100 million when Vitamin Water sold to Coke in 2007. He’s managed to continue to generate the kind of financial footprint that comes from having a solid foundation of knowledge that dictates each of his business decisions.

A man who has had a hand in 50 Cent’s smart financial decision-making is Bruce Seckendorf, who served as the rapper’s former business manager for about 10 years. Born in Jamaica Queens, New York, Seckdondorf founded LL Business Management, and has spent decades working with some of hip-hop’s biggest stars, including Eminem and Timbaland, to help make them more financially viable. By sticking to a principle that includes advising against impulse buys, Seckendorf has built a reputation for great moves and even better results. 

As part of Complex’s Get Money initiative, we spoke with Seckendorf about his career, with the hopes of gleaning useful financial advice for our readers. And he was happy to share some wisdom he’s picked up throughout his years as a successful business manager.

“I tell people, ‘Just believe in yourself, and bet on yourself,’” Seckendorf says, relaying advice for young entrepreneurs. “If you’re going to spend money, spend it on your company, spend it on yourself and your career. Don’t be looking to invest in somebody else’s business and watch them try to make money. Focus on yourself.”
