Learn to compromise. Healthy relationships are not built through winning meaningless arguments. Be willing to back down; most arguments are not of critical importance anyway.
Forgiveness is a powerful and important factor in maintaining healthy relationships. However, real forgiveness also means that we are willing to forget the experience. When we make mistakes, just consider how much we would appreciate others forgiving and forgetting.
Make sure you have at least a few common interests. You do not have the exact interests and hobbies. Having a few common interests can make you closer by doing things together and talking about them. You may have to compromise in some areas like sports, politics, movies, shopping, music, etc. Keep in mind that compromising doesn't mean depriving each other of their individual interests but instead it means participating in each others' interests.
Communicate with each other. A healthy relationship need to develop deep communication. Good, honest, and deep conversation will keep you deeply connected. When in doubt, talk it out. Always keep the lines of communication open in your relationship.
Learn to be humorous and laugh together. Don't take yourself too seriously. A good sense of humor and a pleasant disposition has a magnetic attraction that makes people always want to be in your presence. Be willing to laugh at yourself and be self-deprecating. This does not mean we have to humiliate ourselves, far from it - it just means we let go of our ego. Humor is often the best antidote for relieving tense situations.
A degree of detachment is needed to maintain healthy relationship. People often mistakenly think that being detached means not caring. However, this is not the case. Often when we develop a very strong attachment we expect the person to behave in a certain way. A good friendship based on detachment means we will always offer good will, but we will not be upset if they wish to go a different way.
Keeping a healthy relationship is very important for it have the effect on your daily life. If you fail to maintain it healthy, you may feel upset and a sense of failure, which may lead to bad performance in your work.
