"...situations and surrounding have no lasting impact on our ability to feel joy. Instead, true joy comes from obeying and believing in Heavenly Father and His Son, Jesus Christ, who made life here-and hereafter-'that we might have joy' (2 Nephi 2:25)."
I read this in the Ensign, September 2010 issue this morning. I easily get caught up in my own situations and surroundings, and feel like they sometimes get me down. I'm so grateful to have the Ensign and find articles like this that give me a proper perspective.
