Perhaps we become aware of our age only at exceptional moments and most of the time we are ageless.

To the young there are no degrees of old just as there are no degrees of dead - either you are, or you are not.

Youth is not a question of years: one is young or old from birth.

When we are young... we often experience things in the present with a nostalgia-in-advance, but we seldom guess what we will truly prize years from now.

To be ignorant of what occurred before you were born is to remain always a child.

Youth is not an age thing. It's a quality. Once you've had it, you never lose it.

You can only be young once. But you can always be immature.

Young people seem not to know that they are going to get old, but older people know that they are not going to become young again.

I am not old, but my young way was never the way to age.

Old age that's quick to learn is always young.

No one who is young is ever going to be old.

There is a certain part of all of us that lives outside of time. Perhaps we become aware of our age only at exceptional moments and most of the time we are ageless.

You are only young once, but you can stay immature indefinitely.

To me, young has no meaning. It’s something you can do nothing about, nothing at all. But youth is a quality. And if you have it, you never lose it.
