Apple CEO Tim Cook, the 2015 Commencement speaker, shared words of wisdom and inspiration with the newly minted graduates. ?Work takes on new meaning when you feel you?re pointed in the right direction?otherwise, it?s just a job. And life is too short for that. We need the best and brightest of your generation to lead. You don?t have to choose between doing good and doing well. Find your North Star, let it guide you in life and work and in your life?s work.?
