I discuss the ’3 stages of self love’ that a person goes through as they develop their self esteem – I am not enough, I have had enough, I am enough. He also explains simple principles for ’wiring in’ a greater sense of self esteem into the brain by harnessing the two-way body-mind and mind-body connection. And he will cover how to replace self criticism with self compassion, and share some simple practices, I discuss how vulnerability can be a strength, and why being yourself can be a healthy way to develop self esteem.

The Health Benefits of Kindness
David discusses how kindness impacts mental and physical health and how it is contagious. Research shows that kindness boosts happiness and is also protective against depression. These effects are due to kindness activating and causing physical change in key brain regions. Kindness also impacts the heart and immune system through production of ’kindness hormones’, which are akin to stress hormones, but opposite in their effects. He also discusses the importance of kindness to one’s self – what it is and tools for how to practice it. And kindness is contagious. In fact, it is one of the most contagious of phenomena known to science, with an R-number of between 4 and 5.
