Every life is a new chance, a fresh opportunity for realizing the truth. Yesterday is gone; today is the fresh chance, the new opportunity is now; tomorrow, you cannot be sure of. Every minute is to be welcomed as unique and as valuable, precious in fact. Do not pine over the chunks of time you have wasted. Seize the moment that has come within your grasp.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
