Apparently people, and I am one of them, are having trouble getting PDF's to DL, RPGNow is working on it, so I am going to wait a while to try and DL anymore.
I believe in, what I believe is called, "paying it forward"? Anyways, its the idea if you do good things when you can, you'll have good things happen for you when you need it. Seems to work.
It is also hoped that when Zach sees an opportunity to do good, he will also take the opportunity, because he will remember good being done for him out of the blue.
I don't know how well it works, but I hope it works well.
It is also hoped that others who see good things done will in turn be inspired to do the same kind of actions.
A basic philosophy any good hearted person can practice.
