It is okay to visit your past just don't bring any luggage with you. Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you too, can become great....
Never apologize for showing feeling. When you do so, you apologize for the truth.
To live your life to the fullest, you've got to be a master of economics...after all, time's demand is always far exceeding it's supply.
Whoever follows a crowd will never be followed by a crowd.
