1 On the road to success, the biggest enemy is not the lack of opportunities or shallow qualifications. The biggest enemy of success is the lack of control over one's emotions. When you are angry, you cannot control your anger, which discourages the collaborators around you. When you are depressed, you indulge your own malaise and waste many fleeting opportunities in vain.

　2 A man who can control his passions, desires and fears is better than a king.

　3 The secret of success is to know how to control the power of pain and pleasure without being countered by this power. If you can do this, you can control your life. Otherwise, you cannot control your life.
