The Buddha talks about 7 kinds of suffering. The 7th is the suffering of not getting what one wants.

So I would like you to pay attention to that when it hsppens. What is that like when we dont get what we want?. What thoughts arise?, what emotions arise? and very importantly how does that feel in the body? Also notice your relationship to all those things. Your thoughts, emotions and bodily sensations. How are you relating to them?

This will lead us into the theme of the talk. Seeing suffering, ending suffering.
