" If you can concentrate always on the present, you will be a happy man".....- The Alchemist

Something is not new but hard to completely do. Mesmorized past sometimes make you feel bad about the present and somehow regret the decision that you did. Or if you live for the future, the future is not the future anymore. Beautiful memories may heal your soul during the bad time, however, time flies and things change. Only live for the present, try the best to make it more meaningful, you can save more wonderful memories and smile when you look back.
