We found several who sort of hacked their way into long-term behaviour change. In some cases, this was because of a relationship they didn’t want to lose. One very memorable person told us he just faked it until he made it. He acted like he thought a nice person would act. After about a year and a half, it started to feel natural and even enjoyable. I found that very encouraging. That’s exactly what clinical psychologists recommend: practise the behaviours you want to adopt until habit kicks in. Several people we talked to had also cobbled together their own moral codes, not out of remorse or shame, but because they wanted to become a certain kind of person.
