I'm not you (wife and kids) but I am in teaching (college) and make about the same as you for the job and for poker playing 3/6 and 5/10.

I would never give up the teaching job. Its really not very demanding, the benefits are great, plenty of holidays, and plenty of time for playing poker. The list goes on and several posters have mentioned other benefits.

I havent gotten into 5/10 shorthanded yet but I think I would want to have a little more stability in the game than a speculative .9BB/100 winrate(not doubting your ability or dedication here). Perhaps you could take this sabbatical next year when your poker future is a little clearer?

And during that year off you should probably be doing something to change or further your career (more education/training etc.) along with playing poker if that is what you choose to do.
