"Often the answer to our prayer does not come while we are on our knees but while we are on our feet serving the Lord and serving those around us." -quote by Dieter F. Uchtdorf (Counselor in the first Presidency of the Church of JESUS CHRIST of Latter-day Saints)
Some people really need to remember this. The assumptions and bad mouthing are not only entirely wrong but also make you look incredibly immature. After everything some people go through, it's amazing to see how some things will truly never change. Let your past make you better not bitter, stop throwing dirt. :)
When it comes to choosing joy (among other important things) I believe we are wise to heed this sound advice: "There is room for improvement in every life. Regardless of our occupations, regardless of our circumstances, we can improve ourselves and while so doing have an effect on the lives of those about us." —Gordon B. Hinckley, "Each a Better Person"
