On my work computer, my theme preference follows my mood:

When I'm feeling happy and engaged, dark mode is great. But when I'm feeling down (often in the dark days of January or February), I get a decent lift out of switching back to light mode and adding as much color to the app themes as I can.

"Haven't been happier"?

If I say "it's all downhill from here" does that mean things are getting better or worse?
