"Life is not about arriving at the grave safely in a well-preserved body, but rather to skid in sideways, worn-out, shouting, 'Whoowee! What a ride!!"
I also like "Sing like no-one is listening. Dance like no-one is watching. And love like you'll never be hurt."
Also: "The secret of life isn't what happens to you, but what you do with what happens to you."
