This whole week, why not be a blessing to others and not think about yourself as much?  Sound good?  (The idea came from the Bible:  Philippians 2:3-4 Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interests of others.)

Get creative and surprise some people on campus by serving them in some way:
take out their trash
pick up their food tray
hold doors open
other stuff
