Age is an issue of mind over matter. If you don't mind, it doesn't matter.
Life is a moderately good play with a badly written third act.
You are never too old to set another goal or to dream a new dream.

We don't stop playing because we grow old; we grow old because we stop playing.
The longer I live, the more beautiful life becomes.
Do not regret growing older. It is a privilege denied to many.
Old age is like everything else. To make a success of it, you've got to start young.
The older I grow, the more I distrust the familiar doctrine that age brings wisdom.
