At this very moment you are probably basing your value on how other people value you, even though most of the time, you don’t even know what these people really think. You are assuming what they think based on behavior you interpreted. In truth, most people don’t think about you at all. They are too focused on their own stuff. And if they do think about you, they probably don’t think what you think they think. You are most likely projecting your own fears of not being good enough onto them. What you think they think tells you more about your own opinion of yourself than theirs.
