So, I couldn’t do one without talking a little bit about this where does money come from. Remember we were talking about the retriever, the first dog to get the company started. And they got a trade stock for ideas, capital and talent. Let's talk about how they trade stock for capital. These are the different sources of capital and it's a lot of fun in our classes to dive down and talk about the pros and cons of each one of these. And you'll hear that a lot in here as well.

There are pros and cons on each one. We could sit here for another half an hour and talk about that. It's really a lot of fun to do that. Traditional VC what's the pro? They got lots of money to deploy and for people who really are going for something that would really change the world. They have lots of money to deploy and they got lots of expertise to bring to the table and help. And you'll hear that over and over here again. But what's the downside of VC?

The other one I want to mention here is over and over we see the following, it's really fun to do this one we are teaching this material. It is a process, all...
