Sorry, but I can't do any of the things you list (fall asleep within 10 minutes whether I'm trying to fall asleep for a nap or to go to bed at night; let my mind wander and not get distracted; not worry).

I have a lot of anxiety, which I imagine is relatively common among the developer and tech community. Sleep and peacefulness does not come easily to me. I've tried taking naps at various points over the years, but haven't successfully taken one since I was about 12 or so. Sometimes I'll even lie in bed for 30, 40, 50 minutes to just try and take a short nap. Eventually I'll give up and wonder why I wasted all that time.

This will happen to me even if I'm extremely sleep deprived, and feel very physically and mentally exhausted.
