Tony Perez's Art of War: Be aware of the people who cannot stand your success and your happiness, and who envy and begrudge you for them. They follow you, they monitor your life, and they watch your every move. They typically stay in the background, but some of them are disguised as your fans.

Move forward and progress against all odds, especially because of them. Pretend to be completely ignorant of their existence. Like forking a queen in chess, you improve your status while increasing their suffering.
