Tim Dowling talks to David Thomas

Tim Dowling fell into journalism by mistake; he is not an ambitious man, never was, never will be, but he's fascinated by what it means to be desperately driven to succeed. In his two editions of One to One, he talks to those who have ambition searing through their veins.Today he meets fellow journalist and author, David Thomas. Once the UK's Young Journalist of the Year and the youngest-ever editor of Punch, David believes his Eton/Cambridge education made him feel obliged to succeed.Both now in their fifties, they discuss the merits and drawbacks of ambition: does it lead to happiness and fulfilment or a never-ending nagging discontent and anxiety?Producer: Lucy Lunt.
