Nothing is our fault. We're byproducts of circumstance and genes

We choose nothing about us. Not our phsyical attractiveness, our intelligence, how we're born or raised, how much our parents loved us nor how rich they were, the religion we're inclined to believe, our personality, the environment is complete luck until you grow older, then a mixture of your earlier environment and genes determines the rest, and how good you are at your hobbies and work seems to be determined largely by IQ and talent. So what's the point of all of this if you were dealt a very shitty hand in life? Hell, I question if we even have free will. It doesn't seem like we have any control over any aspect of our lives. We're influenced purely by our wants and desires in any given situation. Why choose a certain career field? Why choose not to? Why do certain things appeal to us more than others? You can choose not to do something, but why is the desire to not do something stronger than the desire to pursue it?
