Man's dearest possession is life, and since it is given to him to live but once.He must so live that dying he can say, all my life and all my strength have been given to the greatest cause in the world, the liberation of mankind
Ostrovski

Muriel Spark:

If I had my life to live over again I should form the habit of nightly composing myself to thoughts of death. I would practice, as it were, the remembrance of death. There is no other practice which so intensifies life. Death, when it approaches, ought not to take one by surprise. It should be part of the full expectancy of life. Without an ever-present sense of death life is insipid. You might as well live on the whites of eggs.
