Few careers are as storied as Bill Belichick's 42-year run.
He started studying football footage and going on scouting trips at the age of 7 with his father, Steve, an assistant coach at Annapolis. He landed his first NFL coaching gig at 21.
Since then, across seven professional teams and five Super Bowl victories, the New England Patriots head coach has gone through every career rite of passage imaginable — from being fired (in Cleveland) to being hailed as a hero (pretty much everywhere else).
And while his story is hardly typical, its many twists and turns have left Belichick with strong views about how to create a successful professional journey — no matter your playing field.
In a recent interview with CNBC at his favorite lunch (and dinner) joint, Mission BBQ, Belichick offered four of his top career lessons for today's young people.
