Your chief task in life is the care of your soul. You should care for your soul and work to improve it, and you can improve it only with love.
Leo Tolstoy
Make it your ambition to lead a quiet life, to mind your own business and to work with your hands, just as we told you, so that your daily life may win the respect of outsiders and so that you will not be dependent on anybody.
1 Thessalonians 4:11-12
The New International Version
We are not at peace with others because we are not at peace with ourselves, and we are not at peace with ourselves because we are not at peace with God.
Thomas Merton
