<human>: My husband is a very intelligent man and is very well educated. The problem is that he is having trouble finding work in his field. He went back to school to become a high school history teacher and there aren't very many jobs. 

I always thought that he didn't try hard enough to get a teaching job. He would send out resumes and apply online and that's it. No followup, no school visits, and he refused an opportunity to fill in as a maternity leave substitute because he was working in retail and didn't want to potentially be left totally without a job after the job ended. 

I take my fair share of blame because I shouldn't have told him that he should be doing more, and I've apologized and we've moved past that (it was several years ago). I'm kind of a know-it-all so I absolutely made it worse so I try really hard to keep my silence now.

The problem is that this was probably 3 years ago and he can't let go of the dream of being a teacher, but he doesn't really go after it either. The result is depression and listlessness. He applies half-assed to any job that floats across his perception. 

He wants to move out of retail and into a career, but he doesn't know what he wants to do. 

So please help me figure out how to help him. He doesn't seem to know what to do, and when he picks something I'm afraid he won't throw himself into it enough to actually make something happen. I don't know how to be supportive and he's going through something I don't understand.

Thank you!
