Overheard "You shouldn't say any of the dumb things that make people sad."
This is a wonderful simple Recipe For Happiness. So many times we are thoughtless and say 'dumb' remarks that just hurt someone for no good reason. Sometimes we think we are giving useful feedback but we aren't. Sometimes we just can't control the impluse to speak. Sometimes we are getting back at someone. But the truth is, these unnecessary comments usually always make the other person feel 'sad.'
