I love the Seattle Seahawks (Super Bowl Champs) mantra “We’re all we’ve GOT! We’re all we NEED!” My fiance told me about it and it’s kind of become our family’s little mantra.
I also highly recommend Coach Carroll’s book: Win Forever: Live, Work, and Play Like a Champion. Check it out if you get a chance. His personal development approach with his athletes is really inspiring and has obviously paid off for him and his team and organization in a big way.
