I taught and I left it. I loved coaching and hated teaching. No actually I like teaching, I hated dealing with discipline problems, and one of my principals.
Just be carful before you get yet another degree and find out that career is just as bad. Maybe work somewhere else and then see what kind of degree you would need to advance in the company/field.
Also, I suggest you quit. Don't just do like most teachers and b!tch about how you hate it. Most teachers are too scared to do anything else and they have their beloved tenure & summer vacation, so they aren't giving that up.
(For all you teachers that say "it's ONLY 10 weeks and maybe really only 8 weeks." Go on a real job interview and tell them you want 8 weeks vacation and see how far you get.)
