Bookshops are filled with rows and rows of pop-psychology and self-help books on the subject of maintaining a mentally healthy relationship with ones self. I am sure this subject is also commonly a primary focus of people receiving professional counseling. Obviously, its an important question for many and one frequently without an easy or comfortable answer. As varied and complex as humans are, there is no doubt that their relationships with themselves are also highly varied and often complex.
I believe, in a sense, each of us is really the only one there in the realm of our own minds and inner-worlds of what we know, think, and feel. In a way, this is the ultimate loneliness. In another way, though, this realization provides an opportunity for unfettered introspection and self-awareness, which can be channeled as a positive force in ones life. In respect to myself, I try to see myself clearly; give myself credit when I deserve it; show myself compassion where its due; and give myself a kick in the butt, as needed.
