Years ago, my friend and I went to the Royal Institution on Albemarle Street in Mayfair for a lecture by Daniel Goleman, the award-winning psychologist who penned the best selling book ‘Emotional Intelligence’. During the Q&A at the end of the lecture, he was asked a question from the audience to which he replied ‘I don’t know’.

I turned to my friend and said ‘Wow, that’s confidence right there’.

In front of over 400 people, this internationally renown expert admitted he didn’t have all the answers related to his specialist subject.

As Plato said, ‘Wise men speak because they have something to say; Fools because they have to say something’.
