As I type this, I'm listening to Nick Clegg talk to Jeremy Vine on Radio 2. It's not an easy chat and inevitably, he's being challenged about the U turn on University fees.  I make no comment about that particular decision but turning back on a decision is an interesting one.

Some people are thrill seekers for whom being afraid is buzz while others are paralysed by fear but they are as motivated by the emotion of fear as the first group.

Perhaps Jan Canfield's got it right with this....
