It's sad when you can't make everyone happy though. It's impossible but at the same time you still hope. You think 'Maybe I can do it ' but you know you can't. But gosh if I had to rely on giving people what they wanted I would have had to write 40 billion different books and even then I wouldn't get it right.
I'm really convinced that our descendants a century or two from now will look back at us with the same pity that we have toward the people in the field of science two centuries ago.
