Generally, I think the fact that we have 'free will' means that we can use our bodies in a physical way that our mind pleases. However there are limits. Some are more free than others. Look at slaves, they would have a lot less freedom than those of us living in wealthy countries.
However, we are mentally free. And can often use this to change our circumstances if we desire. Look at those that have become athletes from poor African nations.
Generally, I think some are more free than others, being trapped physically, or by our own mental limits.
Also, this goes without saying, but obviously even the most advantaged of us have limits. For instance, I wouldn't be able to fly to and walk on the sun by myself. Haha. There are limits.
Any one of us can do whatever it is that we choose to do. However, we know that society comes with its set of constraints, no matter which society one is part of. One can still do as one chooses; the only caveat is that the chooser must deal with the consequences of whatever he or she opts for. We sometimes don't act bravely because we fear that.
The government tries to contain the amount of things that you can done within the country. One example of the government trying to limit freedoms is the NSA. The National Security Agency is in charge of maintaining security within the country mainly by spying on phone calls, computers and others means. Really the NSA stops you from doing things that you could be able to do if you really did have ABSOLUTE FREEDOM.
