No, doubt if we work hard in the past, then our present will be beautiful and cheerful.
But we forget that taking the tress of unsuccessful life, we lose our valuable present time.
Means what we have done that was not important, but what we are doing today that is most important. to get a happy life in future we have to work hard in present.
Take a bold decision today to make your tomorrow cheerful. Life is not ended in just some failed attempt, but each fails attempt makes you stronger mentally to make your next attempt more appropriately.
