There is no point at which you can say, 'Well, I'm successful now. I shall not waste my days in trying to prolong them. The ultimate goal should be doing your best and enjoying it. Obstacles are those frightful things you see when you take your eyes off your goal. Well all live with the objective of being happy, our lives are all different and yet the same.
