Late bloomers also tend to be particularly skilled at turning weaknesses into strengths, and if you can master something you're bad at, you're well-equipped to handle most types of challenges, Grant told "Squawk Box."
"The feeling that something is uncomfortable is a signal that you're about to learn something new," Grant told the New York Times last month.
