Human's Free Will

After reading the first 5 aphorism from the Epictetus' The Handbook I realized what we humans believe we have free will to choose are not all true. I connected this with Jean-Paul Sartre's work on existentialism were he talks that men have the freedom to chose what they are going to be and how they would get to that place. I know that a human has the freedom of becoming who he wants but as Epictetus says, some things are not up to us. Most of the time society decides many factors of our lives. People living in the higher classes can choose to become a business man or a lawyer but as soon as they say they want to become bus drivers society will act on them. They know they wont be accepted and wont be seen as  the same person once they become bus drivers so they decide not to be. If i have learned something over my life is that society has almost every aspect of our lives controlled. If someone gets out of the status quo, somebody will try to stop them. The actual range of human free will is very short not many options are available for us to choose.
