Well I don't have a T; why spend good money on something so common sense, but that's me? On the other hand I have been doing a mood diary using my own scale and recording system - I keep it on my phone and do it whenever I am in a supermarket queue, overtaking on the motorway (just kidding), on the train, having a rest in the park at lunchtime, while waiting for meetings to start and it is incredibly useful. If you cannot deal with another's arbitrary system maybe you should do your own - the important thing I find is to be able to track back and identify events, patterns, actions/inactions that affect mood and develop understanding and strategies to build on this to feel better and be a better person.
