The solutions all are simple — after you have arrived at them. But they're simple only when you know already what they are. - Robert M. Pirsig

There's an old analogy to a cup of tea. If you want to drink new tea you have to get rid of the old tea that's in your cup, otherwise your cup just overflows and you get a wet mess. Your head is like that cup. It has a limited capacity and if you want to learn something about the world you should keep your head empty in order to learn it. It's very easy to spend your whole life swishing old tea around in your cup thinking it's great stuff because you've never really tried anything new, because you could never get it in, because the old stuff prevented its entry, because you were so sure the old stuff was so good, because you never really tried anything new...

If you get careless or go romanticizing scientific information, giving it a flourish here and there, Nature will soon make a complete fool out of you.

When you want to hurry something, that means you no longer care about it and want to get on to other things.
