I think you're simply not asking yourself hard enough questions. I'm making a pivot away from "lol nothing matters so it's everyone for themselves" now largely because my values are not aligned with how I've engaged with society so far.

I reduce my burden on the environment by buying used rather than new whenever I can (for some reason no one wants to consider the upfront heavy burdens of manufacturing things like e-bikes and EVs when the used markets for both are so healthy). I try to avoid contributing to the workplace suffering of others and the normalization of antisocial, anticompetitive business strategies so I try not to encourage those practices by giving money to those who violate those (e.g. Amazon). I shop at overstock groceries (Grocery Outlet) and department stores (Ross, Marshalls) to circularize the economy that much more.

Everyone has priorities, and especially as we emerge out of the pandemic and I observe the working and spending habits of those around me I see that many people value personal, individual conveniences often at the expense of dignity and comfort for others. I want to think I value those things for myself and others and so try to live in accordance with those values. Everyone must compromise but that doesn't excuse at all where exactly we end up drawing that line.
