Years may wrinkle the skin, but to give up interest wrinkles the soul. You are as young as your faith, as old as your doubt; as young as your self-confidence, as old as your fear; as young as your hope as old as your despair. In the central place of every heart there is a recording chamber. So long as it receives messages of beauty, hope, cheer and courage, so long are you young. When your heart is covered with the snows of pessimism and the ice of cynicism, then, and then only, are you grown old. And then, indeed as the ballad says, you just fade away

It does not matter how old or wise you get, life is about believing and listening to your inner voice. I still believe in angels, fairies and butterflies and that keeps me smiling.

But it is common knowledge that religions don’t want conviction, on the basis of reasons, but faith, on the basis of revelation. And the capacity for faith is at its strongest in childhood: which is why religions apply themselves before all else to getting these tender years into their possession. It is in this way, even more than by threats and stories of miracles, that the doctrines of faith strike roots: for if, in earliest childhood, a man has certain principles and doctrines repeatedly recited to him with abnormal solemnity and with an air of supreme earnestness such as he has never before beheld, and at the same time the possibility of doubt is never so much as touched on, or if it is only in order to describe it as the first step towards eternal perdition, then the impression produced will be so profound that in almost every case the man will be almost incapable of doubting this doctrine as of doubting his own existence, so that hardly one in a thousand will then possess the firmness of mind seriously and honestly to ask himself: is this true?

Ultimately we are only as old as we feel in our hearts and minds.

Why were you so old when we met? I answered with the truth: Age isn't how old you are but how old you feel.

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

the confidence of youth counts for little against the cunning of age.

Age isn't how old you are but how old you feel.

Would you be always young? Then be an Anarchist, and live with the faith of hope, though you be old.

Knowledge in youth is wisdom in age.

"He who mocks the infant's faith
Shall be mock'd in age and death.
He who shall teach the child to doubt
The rotting grave shall ne'er get out.

He who respects the infant's faith
Triumphs over hell and death.
The child's toys and the old man's reasons
Are the fruits of the two seasons.

- "Auguries of Innocence

You're only as young as the last time you changed your mind

A Second Childhood.”

When all my days are ending
And I have no song to sing,
I think that I shall not be too old
To stare at everything;
As I stared once at a nursery door
Or a tall tree and a swing.

Wherein God’s ponderous mercy hangs
On all my sins and me,
Because He does not take away
The terror from the tree
And stones still shine along the road
That are and cannot be.

Men grow too old for love, my love,
Men grow too old for wine,
But I shall not grow too old to see
Unearthly daylight shine,
Changing my chamber’s dust to snow
Till I doubt if it be mine.

Behold, the crowning mercies melt,
The first surprises stay;
And in my dross is dropped a gift
For which I dare not pray:
That a man grow used to grief and joy
But not to night and day.

Men grow too old for love, my love,
Men grow too old for lies;
But I shall not grow too old to see
Enormous night arise,
A cloud that is larger than the world
And a monster made of eyes.

Nor am I worthy to unloose
The latchet of my shoe;
Or shake the dust from off my feet
Or the staff that bears me through
On ground that is too good to last,
Too solid to be true.

Men grow too old to woo, my love,
Men grow too old to wed;
But I shall not grow too old to see
Hung crazily overhead
Incredible rafters when I wake
And I find that I am not dead.

A thrill of thunder in my hair:
Though blackening clouds be plain,
Still I am stung and startled
By the first drop of the rain:
Romance and pride and passion pass
And these are what remain.

Strange crawling carpets of the grass,
Wide windows of the sky;
So in this perilous grace of God
With all my sins go I:
And things grow new though I grow old,
Though I grow old and die.

The fear of becoming old is born of the recognition that one is not living now the life that one wishes. It is equivalent to a sense of abusing the present.
