At the end of the day, in your reality, there are only two types of people in this world. People who ARE valuable to you and people who are NOT. Sounds simple but I'm sure you forget from time to time. Sure people in category one, to you, may have different levels of value but they are still valuable. (Your friends, your family, your romantic interests, your peers/coworkers, your work superiors, your subordinates, your neighbors, your religious group, etc.). What keeps them in category one is a healthy relationship with healthy boundaries, growth and mutual benefit (or even a means to an end). When a relationship (of any kind) starts to become unhealthy its important not to become emotional or removed from your center but simply put them in category two without malice. Is no different than reading a news article about a random person in a foreign city or country that has some hardship. You wish that person a well life but they aren't that valuable to your life. Put that same feeling towards people with bad energy and you will reach mental peace. You will no longer harbor any anger or hate towards anyone once you fully master that (it takes practice). If someone is able to push you off center and you keep them around its because they are valuable to you on some level. Depending on the circumstances you might be a masochist. Unless that's your thing I suggest you distill the people in your life and keep those you really care about. Its your job to reach a level of success that you only have people in category one around you and avoid the pitfalls that can force category two people to have a permanent or semi-permanent position. It may very well be that you need to pick your life up, smash it to pieces, and get a whole new environment/ move to a new city. Find your tribe. Treat them well and dont worry about the rest.
