The essentials for happiness are the right company, moderate if sanguine expectations, and a reasonable standard of physical sustenance and comfort; the whole being bedeviled by the belief that there is always something better to be had if only one presses on. — Phyllis Dorothy James (1920–2014) English novelist
• The engaged mind, illuminated by truth, awakens awareness; the engaged heart, affected by love, awakens passion. This essential energy of the soul is not an ecstatic trance, high emotion, or a sanguine stance toward life: It is a fierce longing for God, an unyielding resolve to live in His belovedness. — Richard Francis Xavier Manning [aka Brennan Manning] (1934–2013) American author
