Don't say it if you don't mean it and don't expect more from others than you are willing to do yourself. Follow through even when you get bored or lose interest. Step back and try to see a situation from someone else's viewpoint. Just because something isn't convenient
for you, doesn't make it ok to back out. Doing something for someone else and getting nothing in return can be one of the most gratifying feelings in the world. Be the kind of person to someone else and treat them as you would want to be treated. The world would be a much nicer place to be.
