Free will does not exist, but I suppose it's handy for society at large to pretend that it does.
I don't know why, but I let myself believe for so long that I was the captain of my ship. Now that I embody the fact that everything's out of my control, I have become so much more relaxed and content with life. I do not compare myself with people that are better (or worse) off than me. They lucked into their lives as well.
I am very grateful for everything I have been given. Even the fact that I exist and get to experience this beautiful thing called consciousness. I do not complain much anymore. I work hard to give back. Not that I am rich. But I am strongly inclined to produce more and consume less, perhaps that is because I wish to show appreciation for the gift of the present that I have been given.
And my reaction isn't positive based on only good luck. I've had my fair share of bad luck, and I have been deeply disadvantaged in certain areas of life. But even for those areas, I do not blame myself. Since I believe that it was 100% the role of luck in shaping everything.
I know some people can react to the lack of free will in a negative way, but that has not been the case for me. Would be interesting to dive deeper into why. This realization has also not taken my agency, or my will to live and take action. I know that sounds contradictory, but it's true.
