Understand: people will constantly attack you in life. One of their main weapons will be to instill in you doubts about yourself—your worth, your abilities, your potential. They will often disguise this as their objective opinion, but invariably it has a political purpose—they want to keep you down. You are continually prone to believe these opinions, particularly if your self-image is fragile. In every moment of life you can defy and deny people this power.
