It might be true that there are six billion people in this world, and counting, but nevertheless -what you do makes a difference. It makes a difference, first of all, in material terms, to other people, and it sets an example. In short, I think the message here is that we should never write ourselves off or see each other as a victim of various forces. Its always our descision who we are.
Every passing minute is another chance to turn it all around.
The more you know who you are, and what you want, the less you let things upset you.
