Headstrong persons have made a conscious choice of being what they are. It is indeed very difficult getting along with these kinds of people. You are bound to deal with one at work or even at home. Nonetheless, there are several ways to help you get along with headstrong persons.
Consider confronting the person directly about his or her behavior. Raise your standards on what you are willing to accept. Explain to the person why things were no longer tolerable and tell him or her you want to see will happen. While this person may decline what your demands are, at least you are aware of where you stand and could make a decision based on that.
There are times when you just have to let go as the best option if a headstrong person insists on his or her ways and injures you in some way. You have the choice to let go and move on. Another option would be to remove that person from your life. This is a bit extreme but there are times when this is your best option. This is also to avoid the influence he or she will do in your life. While you may not be able to control everything, keep in mind that you have enough control in your life to avoid dealing with headstrong people.
