Too much talking can hurt you.
It's a lot more important than most people think.
If people see a closet or garage jam packed and totally unorganized they are going to feel like they have to live that way.
I tell people to drive up to their house like they've never seen it before. Look at the mailbox since this is the first thing (prospective buyers) will see. If it needs to be repaired do it. If the door knocker is squeaky, fix it.
