The act of pretending translates into a big conscious effort of willpower that drains your brain of its ability to focus and do deep work.

It's far better to be yourself and risk having people not like you than to suffer the stress and tension that comes from pretending to be someone you’re not, or professing to like something that you don’t.

We don’t actually fool anyone when we're trying to look happy, but our real feelings are far from positive.
