If we choose to derive our sense of personal worth and value from those sources, then we might not ever be happy and fully satisfied.

I could not agree more with this. This is precisely the reason I have been sad deep down for a major part of my life. For a long time, I derived my sense of self-worth from the many elements and viewpoints of people I was surrounded by and not from how I felt about myself. It takes a lottt of courage to bring yourself to love yourself but once you start nurturing those feelings, you can slowly nourish your self-esteem and self-confidence too. It is not easy especially when you are surrounded by undesirable elements but it is doable. Your post is one of those feel-good posts that has inspired me to keep loving myself.
