Money goes around and around and around and around and around. It does. Therefore there is an infinite amount of money in the world.
So if we want some/lots of it, we have to be able to let it circulate in our direction.
I went to a prosperity workshop once where we did the following exercise: we were asked to take a sum of money out of our wallets that we were comfortable with losing, then all stand up and walk around the room, and give the money away. Then sit down when we were ready to. There were about 100 of us.
