I was intrigued about the Stutz documentary because psychotherapists do not tend to disclose a lot of information about themselves in therapy. It's widely agreed that this is not in the best interests of the client. But Phil Stutz has allowed Jonah Hill to make a whole documentary about him - and I think it's brilliant.

Jonah says that his motivation for making the film is to share Stutz and his tools with a wider audience. In the three days between watching the documentary and writing this piece, I've had several friends and also clients contact me about the film. People seem to love it.

So, what are these tools? How can they help people? And what has compelled Jonah Hill to make a documentary about this therapist specifically?

At the start of the film, we get a flavour for Stutz, as he candidly outlines the philosophy that underpins his work. He says that in order to move forward in life, there are three 'Aspects of Reality' no-one can avoid:

• Pain
• Uncertainty
• Constant Work
