I grow little of the food I eat, and of the little I do grow I did not breed or perfect the seeds. I do not make any of my own clothing. I speak a language I did not invent or refine. I did not discover the mathematics I use. I am protected by freedoms and laws I did not conceive of or legislate, and do not enforce or adjudicate. I am moved by music I did not create myself. When I needed medical attention, I was helpless to help myself survive. I did not invent the transistor, the microprocessor, object oriented programming, or most of the technology I work with. I love and admire my species, living and dead, and am totally dependent on them for my life and well being.
One of the ways that I believe people express their appreciation to the rest of humanity is to make something wonderful and put it out there. And you never meet the people, you never shake their hands, you never hear their story or tell yours, but somehow, in the act of making something with a great deal of care and love, something is transmitted there.
None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, it's likely that no personal computer would have them.
Whoso would be a man must be a nonconformist. He who would gather immortal palms must not be hindered by the name of goodness, but must explore if it be goodness.
For nonconformity the world whips you with its displeasure. And therefore a man must know how to estimate a sour face.
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, 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.
