Actually, everyone is, just not everyone admits it. I do. And I am happy as a result. In fact, I think one of the keys to being a happy person is freeing yourself from the fear that people won’t approve of you when you are your dorky little self.
Look at it this way. Trying to figure out how to act so other people approve of you is exhausting and impossible. Trying to act in a way that isn’t how you would normally act is also exhausting and can only be done for short periods of time. So, you might as well be yourself.
Of course, to pull this off and not be ostracized from polite society you still need to be a responsible compassionate and ethical person. But as long as you are, then being a dork will actually help you make true friends that you can actually relax around. And that will make you happy.
