Man arrives as a novice at each age of his life.
Let no one be slow to seek wisdom when he is young nor weary in the search thereof when he is grown old. For no age is too early or too late for the health of the soul.
In youth we learn; in age we understand.
Youth has no age.
I speak truth, not so much as I would, but as much as I dare; and I dare a little more, as I grow older.
Reason, not age, finds wisdom.
Nothing makes one old so quickly as the ever-present thought that one is growing older.
