What ended up making me quit was the bureaucracy. The low pay, on it's own, was awful, but I was willing to put up with it.
Getting screamed at by some office worker because they didn't like how I chose to fill out an attendance report made me go "This is not worth it. I'm better than this."
I was making $16.50 an hour teaching in the early 2000s. I'm now making just under $70 an hour working in the profession I was teaching.
