He actually has a formula for happiness that goes something like genetics + conditions + choices. This is his formula for a realistic approach to trying to achieve the good life. There’s something out of your control, which is your genetic heritage. We’d be foolish to deny that this has something to do with who we are. Psychological research of identical twins shows there’s quite a lot in us which is fixed by genetics. But conditions and choices are things that are more under our control. He talks about how the conditions that you live under affect your happiness – quite small things, sometimes. For instance, he says noise – the incessant noise of living in a city – actually grates on people, and has an adverse effect on their overall sense of wellbeing. He also recommends against long, stressful commutes.
