Be Kind, for everyone you meet is fighting a hard battle. (someone)
Years ago there was a Christian businessman, civic leader, and educator from Lubbock, Texas named B. Sherrod. When asked about his success he said that his philosophy was "There's no such things as problems, only a lot of opportunities to exercise good judgment." I think that's a good mind-set. Life IS hard, but gives us lots of opportunities to exercise good judgment.
Mark, I know exactly what you mean. I am very sad today myself :-(
