For me, right now, it is walking in my beloved Brockwell Park in Brixton. As a psychotherapist, I tell my clients that happiness is the purpose of life. But it is not possible - or helpful - to be happy all the time. For balance, we need to experience a range of emotions (including difficult ones that popular culture seems so adverse to).
The other day I was asked if I wanted to go on a day trip to Brighton. This is normally the sort of offer that I shun as I like to stay well within my comfort zone, and this felt, well...outside of it. However, born out of the sudden frustration with monotony and lack of real human experiences, I instinctively agreed, and what a decision that turned out to be.
