For me, I've always found that taking on a new job is always better if you're unhappy with your current situation. In my situation, everything has always been a step up, like climbing a ladder. None of the jobs I've worked at I can see myself doing for the rest of my life, but by taking that step and actually doing it, I know what I DON'T want to do. I still can't figure out what my calling in life is, but all those previous jobs, no matter how bad they were, helped me in a way.

I don't think you should be afraid of change. If you're not completely happy with your situation, you'll never know if it gets better (or worse) unless you give it a shot. Worst comes to worst, you'll still have experience in education and have that to fall back on.

Whatever you decide to do, congratulations on the job offer.
