"Happiness is not something ready made. It comes from your own actions."

The key to success is to focus on the long term and not get distracted by short-term fluctuations.

Quality is not an act, it is a habit.

The condition of man... is a condition of war of everyone against everyone.

The only true voyage of discovery consists not in seeking new landscapes, but in having new eyes.

未来属于那些敢于挑战现状的人。
