Thinking differently is key to improvement.

There is no better way to improve yourself than an exchange of ideas with peers.

There is a huge difference between thinking we know something and actually knowing something.

An incompetent person in a responsible position may cause huge damage. Such a person should act less and think more.

Don't think you can act perfectly. A perfect person doesn't exist. Always strive to give your best effort, and that's it.

Knowledge is an exceptional kind of property which cannot be lost or used up.
