Welcome my son.
Welcome to the machine.
Where have you been?
It's alright. We know where you've been.

What shall we use to fill the empty spaces,
Where we used to talk?
How shall I fill the final places?
How shall I complete the wall?

Kurt Vonnegut

In meeting men, in many places, I have found that the happiest people are those who do the most for others; the most miserable are those who do the least.... The longer I live and the more experience I have of the world, the more convinced I am that, after all, the one thing that is most worth living for-and dying for, if need be-is the opportunity of making some one else more happy and more useful.

Booker T. Washington
You realize that there's no point in doing anything if nobody is watching.

Chuck Palahniuk - Survivor
