My Dad recently turned 60, and I complied these quotes about age for him:
No wise man ever wished to be younger.
~ Jonathan Swift
At 20 years of age the will reigns; at 30 the wit; at 40 the judgment. ~Benjamin Franklin, Poor Richard's Almanac
We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations. ~ Anais Nin
A man's age is something impressive, it sums up his life: maturity reached slowly and against many obstacles, illnesses cured, griefs and despairs overcome, and unconscious risks taken; maturity formed through so many desires, hopes, regrets, forgotten things, loves. A man's age represents a fine cargo of experiences and memories. ~Antoine de Saint-Exupéry, Wartime Writings 1939-1944, translated from French by Norah Purcell
Old wood best to burn, old wine to drink, old friends to trust, and old authors to read. ~ Francis Bacon, Apothegm
People like you and I, though mortal of course like everyone else, do not grow old no matter how long we live...[We] never cease to stand like curious children before the great mystery into which we were born. ~ Albert Einstein letter to Otto Juliusburger
I have enjoyed greatly the second blooming that comes when you finish the life of the emotions and of personal relations; and suddenly find - at the age of fifty, say - that a whole new life has opened before you, filled with things you can think about, study, or read about...It is as if a fresh sap of ideas and thoughts was rising in you. ~ Agatha Christie
When I can look Life in the eyes,
Grown calm and very coldly wise,
Life will have given me the Truth,
And taken in exchange - my youth.
