A human being can choose what to do, what to become. We are all free. No one but you can decide what you make of your life. If you let other people decide how you live, that is, again, a choice. It would be a choice to be the kind of person other people expect you to be. Obviously if you make a choice to do something, you might not always succeed in doing it. And the reasons why you don't succeed may be completely outside your control. But you are responsible for wanting to do that thing, for trying to do it, and for how you respond to your failure to be able to do it. Freedom is hard to handle and many of us run away from it. One of the ways to hide is to pretend that you aren't really free at all. If Sartre is right, we can't make excuses: we are completely responsibile for what we do every day and how we feel about what we do. Right down to the emotions we have. If you're sad right now, that's your choice, according to Sartre. You don't have to be sad. If you are sad, you are responsible for it. That is frightening and some people would rather not face up to it because it is so painful. He talks about us being 'condemned to be free'. We're stuck with this freedom whether we like it or not.
