After a quarter of a century of personal experience and professional observation, I have come to understand that peace of mind is the true goal of the considered life. I know now that the sum of all other possessions does not necessarily add up to peace of mind; on the other hand, I have seen this inner tranquility flourish without the material supports of property or even the buttress of physical health. Peace of mind can transform a cottage into a spacious manor hall; the want of it can make a regal residence an imprisoning shell.
