The most important lesson I’ve learned for developing new products: You don’t have to be the first person to come up with a product idea. In fact, that will rarely be the case. But you can almost always make an existing idea better. And that’s when you get the big wins.
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.
