Clinton is a big personality who has led a big life and for some of the media conventional wisdom to boil it down to a view that 'all people are really interested in' are a few moments of madness in the Oval Office gets him the importance of the presidency and the significance of his life all wrong.
By asking the question 'Am I happy? ' and via the answer setting out what I mean by happiness there is a political route that can be taken by asking another question - 'Can politics deliver happiness and should it try?'
Friends have suggested that I am the least qualified person to talk about happiness because I am often down and sometimes profoundly depressed. But I think that's where my qualification comes from. Because to know happiness it helps to know unhappiness.
So here is one of my theories on happiness: we cannot know if we have lived a truly happy life until the very end. This view of life and death was reinforced by my close witnessing of the buildup to the death of Philip Gould. Philip was without doubt my closest friend in politics. When he died I felt like I had lost a limb.
