They say that knowing oneself and really understanding oneself is one of the most important things one can do in life. Many people don’t take the time to do so. Also, our relationships with others our a reflection of the relationships we have with ourselves. In other words, our feelings toward other people are representative of the feelings we have toward ourselves.
So my question is are others necessary to help us understand ourselves?

Of course, this is how we know how we communicate with others to help to get to know and better ourselves. you dont’ get to know yourself by locking yourself in a room, do you?
no.. you get to know yourself and what you are made of by communicating with other people. When we communicate and who we choose to communicate with is a direct reflection, it shows whom and what we appreciate and whom and what we have things in common with, who we can understand and who understands us.
