Is There a Set Purpose to Life that Must be Discovered or is it Something that is Personally Given to Life by Each Individual?

I don't think that there is a set purpose to life. I think that each individual is free to create their life's purpose or change it at their own will. If there were a set purpose to life, I feel people would go mad trying to figure it out; asking questions on one can or could ever know the answer to. I would speculate that if there were a set purpose to life, life would be boring. You would already know what you were meant to do, which in my opinion, takes the choice and imagination out of your thoughts for the future. Another argument against a set purpose is the idea of free will, if humans have free will, their purpose cannot be set. If it were to be set, free will would be an illusion because everything they do, though it seems to be their own thoughts and ideas, would really just be part of a purpose that was already planned out for them before they were even aware of it. All of this, I suppose, plays right along with Sartre's claim that "we are condemned to be free," since I am suggesting that our purpose is our own to create.
