Learn to say Noโand to be rude about it when necessary. Otherwise you will not have time to carry out your duty, or to do your own work, and certainly no time for love and happiness. The termites will nibble away your life and leave none of it for you.
Robert A. HeinleinThere comes a time in the life of every human when he or she must decide to risk โhis life, his fortune and his sacred honorโ on an outcome dubious. Those who fail the challenge are merely overgrown children, can never be anything else.
