We were deliberately designed to learn only by trial and error. We're brought up, unfortunately, to think that nobody should make mistakes. Most children get de-geniused by the love and fear of their parents - that they might make a mistake. But all my advances were made by mistakes. You uncover what is when you get rid of what isn't.

The discovered reality made the scientists exploratory work seem relatively disorderly.

We live in a decaying age. Young people no longer respect their parents. They are rude and impatient. They frequently inhabit taverns and have no self control.

Never forget that you are one of a kind. Never forget that if there weren't any need for you in all your uniqueness to be on this earth, you wouldn't be here in the first place.

In fact, it is always because of one person that all the changes that matter in the world come about. So be that one person.
