This is something you have to believe, embrace and be confident about. Success and greatness come from within. Stay positive, keep going even if you fail many times. Failure is part of success. Focus on what you want, and don’t think how far you have to go to get there, think about how far you’ve become from what your mind was two, three or four years ago. This is your time, this is your life and you’re going to make the best out of it, so believe and keep going on.
