The truth is not always beautiful, but the pursuit of truth is always beautiful.

Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.

The key to solving complex problems is to break them down into manageable pieces.
