I wish that I had kept my old messages. I had a hotmail that I used in high school and when gmail launched I thought to myself "I'll never need that old stuff" and I let it expire.

I would love to go back and read the emails I was sending in high school.

That said - if there was a filter to mass delete everything in the "promotions" folder - I'd jump on that.

I found this advice also holds in developing countries. Twice now I've had Google maps direct me off a congested major road into some really sketchy areas.

I haven't completely stopped, but I was able to change enough to stop making them bleed and hurt.

There were a couple factors for me. First, I started to recognize that I'm some form of neurodivergent and biting my nails was a stimming behavior for me. Sometimes it was stress related but if you look up stimming behaviors there are a number of other things that can trigger it.

I made a conscious effort to replace biting with something else. In my case I found I was still putting my fingers to my mouth subconsciously so I switched from biting to using my teeth to scrape under my nails. It sounds gross, but my nails are always so short that there is nothing under there. I still don't catch myself sometimes and bite them, but I catch it often enough that my nails are super short, but not painful and bleeding.
