Experience is the only real teacher and if you keep a diary you get three bites at educating yourself - when it happens, when you write it down, and when you reread it and realise you were wrong. Making mistakes is part of life. The only things I would feel ashamed of would be if I had said things I hadn't believed in order to get on. Some politicians do do that.

When Mandela voted for the first time at the age of 76 there was a lot of grown men, including me, wept buckets. That was what it was about. It doesn't solve things, but it gives you the mechanism to hold to account the people with power.
