1, if the heart is young, the years are not old; If you are not old, you will be happy to be old.

2. Time is not regretted by experience, but enriched by vicissitudes; Life doesn't grow old with time, but changes with mentality.

Life grows old because of youth, but not because of mentality. The past days were yesterday, but the past days are today.

4. If you are young, the world is not old; When the heart is old, life will be barren.
