You're only young once, but you can be immature forever.
Before you know it it's 3 am and you're 80 years old and you can't remember what it was like to have 20 year old thoughts or a 10 year old heart.
I am willing to admit that some people might live there for years, or even a lifetime, so protected that they never sense the sweet stench of corruption that is all around them - the keen, thin scent of decay that pervades everything and accuses with a terrible accusation the superficial youthfulness, the abounding undergraduate noise, that fills those ancient buildings.
I am not young enough to know everything.
I've got a great ambition to die of exhaustion rather than boredom.
Both life-planning and the adoption of lifestyle options become (in principle) integrated with bodily regimes. It would be quite short-sighted to see this phenomenon only in terms of changing ideals of bodily appearance (such as slimness or youthfulness), or as solely brought about by the commodifying influence of advertising. We become responsible for the design of our own bodies, and in a certain sense noted above are forced to do so the more post-traditional the social contexts in which we move.

Nor do we accept, as genuine the person not characterized by this blushing bashfulness, this youthfulness of heart, this sensibility to the sentiment of suavity and self-respect. Modesty is bred of self-reverence. Fine manners are the mantle of fair minds. None are truly great without this ornament.
Were art to redeem man, it could do so only by saving him from the seriousness of life and restoring him to an unexpected boyishness. The symbol of art is seen again in the magic flute of the Great God Pan which makes the young goats frisk at the edge of the grove. All modern art begins to appear comprehensible and in a way great when it is interpreted as an attempt to instill youthfulness into an ancient world.
The hope is that if we can increase youthfulness, we can postpone age-related diseases.
I am so glad that I am young, so that I may give my youth to you.
It was his optimism that Freud bequeathed to America and it was the optimism of our youthfulness, our freedom from the sterner, sadder tradition of Europe which enabled us to seize his gift.
Many of the most successful men I have known have never grown up. They have retained bubbling-over boyishness. They have relished wit, they have indulged in humor. They have not allowed ‘dignity’ to depress them into moroseness. Youthfulness of spirit is the twin brother of optimism, and optimism is the stuff of which American business success is fashioned. Resist growing up!
