Wednesday, night, I started to feel something gross in my head, like a sinus infection. I woke up Thursday feeling pretty crappy, and by late afternoon, bailed on work. I was intent to just go back to it later after a nap. I woke up three hours later with a fever. Friday I woke up again, thinking I could work for a bit (this may be the curse of remote work, by the way), and realized upon getting out of bed that there was no way.
When I finally woke up, after 11 that morning, fever still kicking my ass, I realized at that moment that I had been neglecting to take care of myself. In fact, I had the bigger moment of realizing that I had fallen into the bigger pattern of putting most other things in front of taking care of myself. I should totally know better.
One of society's least endearing beliefs is the one that insists you put everything else in front of your needs, because that's what makes you a good person. That's total nonsense. There is no doubt that being a selfish dick isn't good for you, and definitely not others, but it doesn't mean that you can't take the time to put #1 at the front of the line. If you're totally selfless, I can absolutely promise you that a time will arrive where you start to loathe and resent everyone and everything around you. That means family, friends, work, chores... everything. There are perfectly acceptable times to let everything be about you.
Take care of yourself.
