St. Thérèse of Lisieux (often referred to as The Little Flower) was a French nun and one of the most popular Roman Catholic saints. She is particularly known for her Little Way, which speaks of not of doing great things but of doing small things with great love.
I particularly like her Prayer for Dealing with Difficult People. Even if you substitute the name of your particular Higher Power the words are still powerful.
