I wish I had heard this right after college.

I ended up in a toxic, highly abusive environment at work. I should have walked out on day one. But of course, I didn't because I thought quitting was just a sign of weakness and a sure sign that I just wasn't cut out for it.

The "never give up" advice that I'd always heard only helped me internalize all that toxicity and double down in an effort to "fix" the situation.

Sure, no job is perfect. Most have a few crappy elements to them. But there's a difference between tough and toxic.
