I don’t think I can pick just one, so here are some of my favorites:
“I wish I were a glow worm, because a glow worm is never glum. Cause how can you be gloomy when the sun shines out your bum?”
“When you get the end of your rope tie a knot and hang on”
“Life isn’t about waiting for the storm to pass, it’s about learning how to dance in the rain.”
