One of the most beautiful things in life is Nature. We could live 200 years and yet, we'd still not get to enjoy all there is to be seen. So, since you probably will keep being a busy person, without time to do nothing, you should at least STOP and watch the sunset from time to time.
That will remind you of how tiny we are and how life moves pretty fast. Or at least you'll get a good time. Also, you should all visit each photographer's photostream at flickr. These guys put lots of effort in these pictures! Let's show them our appreciation! Quoting Ferris Buller:
"Life moves pretty fast. If you don't stop and look around once in a while, you could miss it."
