"I know not what tomorrow will bring", these were Fernanado Pessoa's last words. I can see some wisdom in them. One can never know what may happen. We may be better or worse tomorrow. It may rain or be a shiny day. We could start a new life or die. Maybe we could see the happiness in everything, or stuff could be all dark. Anyway, there's one thing we can know: our look makes a big difference. We can rejoice and even be thankful for the rain, for the death, and for the darkness, why not? Somebody who has never been in the darkness can't know how great is the light!
Well, it may sound optimistic, unrealistic, whatever you want to call, but I do believe it.

"I'm an optimist. It doesn't seem much use being anything else." (said Churchill)
