Never, in peace or war, commit your virtue or your happiness
to the future. Happy work is best done by the man who takes
his long-term plans somewhat lightly and works from moment
to moment "as to the Lord." It is only our daily bread that we
are encouraged to ask for. The present is the only time
in which any duty can be done or any grace received.
