The sure thing boat never gets far from shore. When you cannot make up your mind which of two evenly balanced courses of action you should take - choose the bolder. You can become a winner only if you are willing to walk over the edge. If we don't change, we don't grow. If we don't grow, we are not really living.
Growth demands a temporary surrender of security.
Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. There is no safety.
