It is a wonderful thing to exchange ideas. An idea is the only thing you can exchange with someone else and end up with more than you began with. For example: I have a dollar and you have a dollar. We exchange them. Now what to we have? We each have a dollar. An Idea on the other hand.... I have one, you have one. We exchange them, and each end up with two.. and not only that... we can build from there.... wonderful.....
