What if at work you let your co-workers know how important their job is to making everything work better around the office, or the lab, or the store? What if you let someone go to break ahead of you? Or in line at the cafeteria?
What if in the drive through you paid for food for the car behind you? Just once?
What if, just for one day, you put others first every time you had the opportunity? Not saying you should do this all of the time...just for one day.
