The big lesson to me this week has been to resist paying too much attention to the News – to avoid PM on Radio 4, to switch off Channel 4 News, to put the newspapers to one side. Had I done so, the non-stop commentary would never have sent me into a spin and a more sympathetic balance might have been maintained. But this is the nature of politics today. It is not about balance. It is about knocking us out of equilibrium. A lesson learned.
