Pope John XXIII, on what is still possible

I love this quote from Pope John XXIII, now saint.  It is so inspiring and motivating. It exhorts us to never give up on our dreams or unfulfilled potential or what is still possible to do.

Winston Churchill is someone who really walks his talk. He applies to himself what he talks about. So he embodies what "continuous effort" can achieve.

The photo is a young man who kept on repeating what he is shown doing here. He just kept on diving, then going back up and diving again. I actually titled this as "I believe I can fly" when I posted this photo in my RedBubble site.
