How many people try to save the world while those closest to them are made to pay a steep price? Their priorities are wrong. Is the good guy only good when others are watching?

Mind your own business. Figure out when it is appropriate for you to intervene and when are you sticking your nose in where it doesn't belong.

Hide your talents, work hard until you die, give everything you have to others, and bear all hardships with patience. This is the life of a true warrior.
