Pay close attention to this video, people. Not because it's Steve Jobs, but because it's some of the best advice you will ever receive: Steve Jobs giving you his vision of life and how you can make a difference.
"When you grow up you tend to get told 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, have fun, save a little money.
That's a very limited life. Life can be much broader once you discover one simple fact: Everything around you that you call life was made up by people that 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."
The man certainly followed his own words. [Thanks Nick!]
