I agree. 2024 was the first year in a long time where I made absolutely no resolutions except surviving the year, and I don't miss those lists one bit. Don't stress yourself out about resolutions and having to become a new you. I'm sure the you right now is perfectly lovely. A new year may be a good motivation to make some changes, but motivation dies and inspiration fizzles. Tedious persistence is unfortunately the only reliable path to any improvement, and that can start on any random wednesday, when/if you feel like it.
Nature's "new year" comes with the spring, so humans must be the only living beings who go absolutely apeshit in the middle of the winter to get things going for no good reason.
