I mean, the things we become, you are surrounded by people who hate the choices of others, people who lack common sense, people who don't think they need to work on themselves.
Then you naturally stagnate and grow resentful too. You are surrounded by people who are respectful of each other, people who are focused on their own business, people who are enthusiastically seeking to get better for their own sake, but also for the sake of their family and friends.
Then you suddenly become a more self-confident version of yourself and you naturally attract happier days.
