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 it should be something you're passionate about.
This, he says, makes focusing not seem like a chore. In his interviews with highly successful people and billionaires over the last 10 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 says.
St. John says successful people hate moderation, which helps them to channel their focus. "It's all or nothing," he says. He 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."
