From the Silicon Valley Historical Association Steve Jobs (1994 interview), there’s a clip from Steve’s early years where he explains an important realization that he’s had about life:

When you grow up, you tend to get told that the world is the way it is and your…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 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…you can build your own things that other people can use.

The minute that you understand that you can poke life and actually something’ll…you know if you push in, something’ll pop out the other side…that you can change it, you can mold it. that’s maybe the most important thing.
