Feeling somewhat empowered by this, I even realized that I was allowed to, uh, buy books and read them!
I've got Statistical Rethinking with a mind to work my way through it once I can sleep more than four hours a night.
Frank Harrell's BBR lectures have been immensely useful in rethinking some things I thought I knew.
But I also have a renewed hope, vigor, the acceptance that it's okay not to know *everything* right now, but that I still can learn new things when I try.
But I personally got over it (sort of) by empowering myself to learn new things.
It's okay to not know something, buy a book, feel a bit lost, work your way through it.
