It can be powerful to immerse yourself in environments where your desired identity is the norm . The idea is that habits are easier to form and maintain when they're supported by the culture and norms of the group you're a part of.
For example, if you want to be more physically active, joining a fitness club where regular exercise is the norm can help reinforce this habit. Being around people who embody the identity you aspire to adopt makes it easier for you to engage in the behaviors that align with that identity.
This concept taps into the powerful influence of social proof and belonging, which are strong motivators for human behavior. When you see others around you engaging in certain habits, those actions become more normalized and attractive to you, making it easier to adopt and stick with them.
