I will give you one important piece of advice - do not fight your enemies and do not worry about your loved ones. Never get involved in malicious relationships with others. Do not waste your time on litigation. On the other hand, do not get too involved with family and friends. Do not get close to people to the point where it bothers you.
The golden rule is to be neither too close nor too unfriendly. Just stay neutral. Do not give people reasons to love you or not love you a lot; stick to this stance.
