"Right Livelihood" is a Buddhist term that has led me to establish The Helm Group. It has stuck with me since I first heard it many years ago.
"To practice Right Livelihood, you have to find a way to earn your living without transgressing your ideals of love and compassion. The way you support yourself can be an expression of your deepest self, or it can be a source of suffering for you and others."
"An expression of your deepest self." That's the part that really stuck.
