When you grow up, you tend to get told that the world is the way it is, and your life is just to live your life inside the world. Try not to bash into the walls too much. Try to have a nice family life. Have fun, save a little money. That's a very limited life. Life can be much broader, once you discover one simple fact, and that is everything around that you call life was made up by people who were no smarter than you. And you can change it. You can influence it. You can build your own things that other people can use. Once you learn that, you'll never be the same again.
