Tune it out when you need to! I think that sometimes people feel this weird obligation to be sad, almost, like you aren’t being a good leftist if you aren’t sad about how shitty the world is. This is nonsensical, and self-defeating. Ultimately, we really do only have this one life to live, and we should absolutely make the best of it, and be the happiest that we can be. You don’t have to be sad to be a good leftist. You just have to do the best with what you have.
