What do you spend most of your time thinking about?

I've tried to become less obsessed with current events because I realized the toll it was taking on me. I've essentially decided to ignore any news about COVID, the doom-and-gloom cycle is hard to get out of and there is nothing I can do about it, so having periodic moments of panic where I think "the pandemic is never going away, we're going to be wearing masks forever, etc." was doing me no good. The environment is another one; I live in the West so I became obsessed with wildfires and monitoring where they were happening, whether they were going to target any place I care about (they did and destroyed a beautiful place that will never be the same again)...but again, I can't do anything about it, I can't fight a wildfire, I can't stop nature. So I've tried to dial it back and focus on smaller-scale, more cerebral and insular things. I've tried to make my daily life run more smoothly and devote my time to thinking about things that are timeless, like literature and art and philosophy. It's better than panicking about the physical world falling apart. So far it's been working but every now and then I'm tempted to get sucked back into the negative spiral.
