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.

"today or tomorrow we will go to such and such a town and spend a year there, doing business and making money.". Yet you do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little while and then vanishes. Instead you ought to say, "if the Lord wishes, we will live and do this or that.". James 4:13-15
