If faced with the fact that there is no free will, it seems like you have three choices, No, not choices, cause choice implies freedom to choose. Three paths then?
The first: You ignore it all, simply move on as if you did not know, or do not care. Retaining all the illusion of choice and freedom you always had.
The second: You become a spectator of your own life. Even with all being only deterministic chain reactions, your personal story might still be exciting. Just sit back and watch. Enjoy the show that is your life, as it unfolds. How does the story end?
The third path: Conscious thought, the belief that even though controlled by genes and environment, observing our actions provides us with the capacity to rewrite ourselves. Becoming the authors of our own stories, instead of just the looker-on.
