Did Steve jobs ever say, "Hey, I want to make a $100 million company?" That was never in discussion. He said, "I want to make insanely great products. Then I want to get really good at marketing because I want everybody in the world to have an Apple device, and the way to do that is to get really good at marketing."
One way to aim high is to try to make something that people will care about in a hundred years. Not because their opinions matter more than your contemporaries', but because something that still seems good in a hundred years is more likely to be genuinely good.
haven't read yet but was recommended on a podcast - excerpts from the author of Zen and the Art of Motorcycle Maintenance on quality and related concepts. will edit this note with takeaways once i've read.
