You can't depend on your eyes if your imagination is out of focus. Age is an issue of mind over matter. If you don't mind, it doesn't matter. There is no sadder sight than a young pessimist. A poem is never finished, only abandoned.
Some people are so afraid to die that they never begin to live.
Greatness is the dream of youth realized in old age. A witty saying proves nothing. I disapprove of what you say, but I will defend to the death your right to say it. Doubt is not a pleasant condition, but certainty is absurd. I am not young enough to know everything.
