Aging is not lost youth but a new stage of opportunity and strength.

You are never too old to set another goal or to dream a new dream.
Don't worry about old age; it doesn't last that long.
Age is an issue of mind over matter. If you don't mind, it doesn't matter.
I never feel age... If you have creative work, you don't have age or time.
The older I grow, the more I distrust the familiar doctrine that age brings wisdom.
The longer I live, the more beautiful life becomes.

Old age is like everything else. To make a success of it, you've got to start young.
I never act my age. I act like I feel. I feel like I'm in my 20s.
The secret to staying young is to live honestly, eat slowly, and lie about your age.
Age is no barrier. It's a limitation you put on your mind.
You can't help getting older, but you don't have to get old.
