The Center for Faith and Business has this listing of the 10 Commandments with a short paragraph showing practical ways to apply those commandments to your work life. The one which spoke best to me was the 1st commandment:
Trust in God only.
Trust in no one but God. People will disappoint you. God created you, He loves you, and has a wonderful plan for your life. He is too good to do wrong, and too wise to make a mistake, even when the “fur is flying.” Let His peace abide in you.
