Keep silence for the most part, and speak only when you must, and then briefly.
I am involved with 'Write Girl,' which is such a great organization, because they go into inner city schools and work with underprivileged girls to pair them up with other writers. And it gets them learning to express themselves and become familiar with their own voice. They have a 100% success ratio getting those girls into college.
All human beings have failings, all human beings have needs and temptations and stresses. Men and women who live together through long years get to know one another's failings; but they also come to know what is worthy of respect and admiration in those they live with and in themselves. If at the end one can say, This man used to the limit the powers that God granted him; he was worthy of love and respect and of the sacrifices of many people, made in order that he might achieve what he deemed to be his task, then that life has been lived well and there are no regrets.
