(CNN) -- Advice can be a tricky thing. If it's unsolicited advice from your mother -- or any advice from your mother, really -- it'll likely go in one ear and out the other. But if that same advice comes from a favorite mentor or best friend, it can change your life. Dhani Jones is a former NFL linebacker, entrepreneur and author of "The Sportsman: Unexpected Lessons From an Around-the-World Sports Odyssey." He's shared his best advice with CNN for a new Digital Studios series called "Be a Champion." In the video above, Jones says he always tries to make a great first impression by dressing well -- without spending a lot of money. What's the best piece of advice about life you ever received? How did it change your behavior or attitude? Tell us in the comments below and on social media using the hashtag #BeAChamp. Your answer could appear on CNN.
