People don’t really care about what you’re doing, they are too busy worrying what other people are thinking about THEM. I think a lot of people need to hear this. It seems to me that everyone is caught up in their own head, always thinking about what everyone thinks of them. But that’s not the case. People are, by nature, inherently narcissistic and self-absorbed. And this causes them to think exactly the same as you, wondering what everyone thinks of them.  This creates a cycle where everyone thinks about what everyone thinks of them, when everyone else is busy thinking the exact same thing.
