Anything that is in the world when you're born is normal and ordinary and is just a natural part of the way the world works. Anything that's invented between when you're fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. Anything invented after you're thirty-five is against the natural order of things.

— Douglas Adams

Man verdirbt einen Jüngling am sichersten, wenn man ihn anleitet, den Gleichdenkenden höher zu achten, als den Andersdenkenden.

One degrades a youth with surety, when one directs him to appreciate the like-minded thinkers more than those who think differently

— Friedrich Nietzsche
