From there, a community developed. I and others in this community realised that effective altruism could be applied to all areas of our lives – choosing a charity, certainly, but also choosing a career, volunteering, and choosing what we buy and don’t buy. On the basis of this, in 2011 I co-founded 80,000 Hours (a name that refers to the number of hours you typically work in your life), which provides advice and coaching on how to choose a career that will allow you to make the most difference.
