"If I could only live my life over again, I would live it much differently than I did in the past." This is a thought which practically all people ponder at some time or other．
"Why didn't I study harder when I was in school？" a person asks himself. "Why didn't I take better care of my health？" "Why didn't I save my money？"
Different people think of different things which could have greatly changed their lives, if they had only acted differently in the days gone by.
Such thoughts, however, are really to no point. We cannot relive our lives. The past is gone and will never come back. We cannot change any of it.
The future however, remains. And it is the future which is important.
It offers us an opportunity to make up for the deficiencies of the past.
Were we careless about our studies in school？ There is still time to learn．
Did we neglect our health and squander money in our youth? We can be careful about these matters in the future．
Have we been proud and domineering in the past？ We still have a chance to become gentle and kind.
Have we neglected our parents? We can make it up to them by being especially devoted to them in the months and years that lie ahead.
We cannot relive the past. But we can use the experience of the past as an aid to success and happiness in the future．
