I never really feel I have "dull" sessions, but then I don't get bored too easily (I welcome a little boredom now and then actually). Do we have sessions that aren't particularly intense on occasion? Sure, but that doesn't make them dull or unimportant. Sessions can be productive on a variety of levels and that doesn't always mean intensity. It may be we were able to set some goals or come up with a plan. Not intense, but certainly productive. Even sessions that consist of what seems like chit chat can be productive if I leave the session feeling good about myself and life in general.
