Knowledge - There's always much information that we are able to store in our minds. These things can help us get through with the next experiences we are going to encounter over the coming days or years in our lives. Sometimes, it's not enough for us to only learn these things but we also want to spread and share it. You can blog, you can write a book, you can discuss it with friends, you can forum sites, or maybe you can be a professor or a teacher. These are just some ways to spread it.
