How to Be Optimistic (Despite Everything)

Comedian Nick Revell explains why he manages to be optimistic - despite all the evidence.

"These days it's perhaps easier than ever to get pessimistic at the state of the world; I've had periods when I would wake up in the morning, check the news and ask myself if it's even worth moisturising. But I have a very positive attitude to life now. So let me take you on my journey of discovery."
