Lao Tzu said that without
going anywhere, one can know the whole world; Without looking out of the
window, one can see the way of heaven and that the further one goes, the less
one knows. It is better to travel with a pocketful of feathers than a large
stone on one’s back. No, we don’t have to know everything; we don’t have to
understand everything. Your mind isn’t big enough to get itself around
everything. Just make sure you understand what is truly important and what your
place in the universe is.
