I guess? I feel like this is one of those instances where it feels intuitively correct but probably isn't. Ignoring that, intelligence is only one dimension of success as well. I know plenty of wickedly smart people who flounder and do nothing because they'd rather stew in mediocrity than ever put themselves in a situation where they might fail. Seems like some unnecessary flavour text around what is essentially: "Do your thing and don't worry about everyone else."
