Negative Nancy/Debbie Downer

Sometimes I catch myself not being the best version of myself.  I say something that really doesn't contribute toward a more positive outcome.  And it disappoints me.  My friends will still love me anyway, but it's certainly annoying when I hear those words come out of my mouth.  When they try to help me out, and I shoot down every one of their ideas- no good.  Listen! Listen before you immediately dismiss their assistance.
