Don't assume people are mean

First, people’s thoughts are mostly focused on themselves. Secondly, they are directing their thoughts towards their relationships, but only how those affect them. That leaves little room for empathy.

This means there is no point in feeling embarrassment; your self-judgment is overwhelmingly larger anyway. Also, people are not intentionally mean, usually. And at last, relationships are your job to maintain! 

Don’t wait to be approached, people are too absorbed with themselves.
