Defining introversion and extroversion

Do you ever feel the world is stacked in favour of the extrovert people – the most gregarious, the most outwardly confident, the perhaps sometimes sharp-elbowed, the loudest? What can natural introverts do to try and level the playing field and create a positive impression? Evan Davis asks Richard Etienne from the Introvert Space, Clare Farthing from South Somerset meet ups and Heather Vernon, co-founder of Woburn Partners. Produced by Bob Howard.
