The secret of life: Is to have a task. Something you devote your entire life to. Something you bring everything to, every minute of the day for the rest of your life. And most importantly, this thing, it must be something you can not possibly do. -- Henry Moore
For me, I have chosen to save the world from itself. Impossible, I know. But that is the point. If I can live my life as an example for others, then maybe I can effect someone else to join the cause.
Maybe it's time to start looking for new ways to do things.
