Life is not a dress rehearsal because you cant go in same day, in same time, in same date and the day will past each day. As example today you having an accident. You never can going back the day you having an accident, the day will past and just only become a memories and experience. Based on experience make us survive and live today to continue our journey of life. Grab that opportunity by doing the important thing in your life and enjoy it than you will earn for it.
