Last year there was a thread where people were recommending purchases they made or gifts they got that were unexpectedly brilliant. I got sleep headphones based off that thread for my birthday, and they have honestly been amazing - have helped me sleep better as I no longer turn to my phone and doom scroll when I wake up, but just put on a podcast or a meditation session and drift off to sleep. (Also got an acupressure mat that has been much less useful).
As my birthday and that of my kids, and as well Christmas approaches, I was hoping it is time to make a new similar thread maybe we could all find the next thing that changes our lives.
