On the other hand, if you can’t change the other person, maybe you should just accept them as they are. That’s another strategy that sometimes works, but this one can also lead to frustration and even resentment if your needs aren’t being met.
There is, however, a third alternative for those times when changing the other person and accepting the other person as-is are both unworkable for you. And that option is to change yourself in a way that solves the problem. This requires that you redefine the problem as an internal one instead of an external one, and then the solution will take the form of an expansion of your awareness and/or a change in your beliefs.
