Stay away from negative energy. Don't pay attention to it, and definitely don't take it seriously. Treat each other sincerely, but set high expectations. Why should you make unconditional sacrifices? The key is that you make unconditional sacrifices. If you resist slightly, you'll say something unpleasant.
Very often, you can't see your efforts, think it's reasonable, have no gratitude, but then you receive criticism. In such cases, why bother too much? People are mutually related. Without sincere treatment, there's more complaining. When you get tired of listening, it's really annoying.
Don't reflect, just keep talking about those same things every day. It's very boring. Focus on doing your own things.
Approaching anyone is a disaster. All the shortcomings are magnified infinitely. People start to dislike each other. It's okay.
Just walk away if you can. Listen less and do your own things well. Let your energy return to yourself. Don't be disturbed by everything outside.
