"How do I know what I think until I hear what I say?"

There is much truth in that old Irish saying, quoted this week by Charles Handy. Or, as the great management guru Peter Drucker said when Charles asked him how he learnt. "By listening", he said, "to myself".

I have always found that I work out my view or understanding of something by talking about it. It gets my brain connections working. And I don't think its just me. The logic is simple. If you want people to work out what they think about something, give them time to talk about it. Break up your presentation with time to talk to your neighbour. It is a very simple technique but one rarely used.

Charles was talking at a brilliant Common Purpose event, organised by the irrepressible Julia Middleton, where a range of leaders gave one hour presentations - giving those of us attending a choice every hour of which to go to. Charles had other pieces of wisdom to share:

• "In 15 Indian languages there is no word for teach, only for learning."
• "Great teachers tell stories. That is really all they do."
• "How can you turn your students into teachers so they really learn?"
• "Everybody has something good in them"
• "You need a purpose that is bigger than yourself - a passion. You win people over with the infection of your passion, never by force feeding them."
• "You need to keep on living vicariously for the triumph of others, taking secret pleasure in their achievements that only you know you have played a part in."

A very wise man, of great humility. I felt lucky to have been able to hear him.

And a very interesting thought from a member of the audience: "If you are not a bit scared about delegating to somebody, then you are not delegating enough." I might come back to that one.

Note to Julia: I know the event was under "Chatham House rules" (confidential) but Charles Handy was kind enough to give me permission to quote him.
