St. John says that when you’re young, it’s okay to initially dabble in a few things. But there comes a time when you need to “just pick one thing” and find your passion.

This, he says, makes focusing on one thing not seem like a chore. In his interviews with highly-successful individuals and billionaires over the last ten years, St. John says they rarely get excited discussing money. It helps that they have some, he says, but it’s never the focus.

“But when you talk about their passion, they light up,” he adds.

St. John says that successful people hate moderation, which helps them to channel their focus. “It’s all or nothing,” he says. The success expert notes that there is a major distinction between concentration and focus.

“Concentration is being able to get something done in the short-term,” explains St. John. Focus, meanwhile, is paying attention to one thing long-term.

Most importantly, say St. John, successful people are not jacks-of-all-trades.

“Successful people aren’t great at everything,” says St. John. “They are great at one thing and suck at everything else. If you focus on too many things you won’t be able to spend time on what makes you great.”
