Character Occupations

I'm trying to figure out just what my hero in my (latest-sort of) wip does for a living. Currently he's a fifth grade teacher. Hey, my heros are usually regular joes. I tossed around the idea of making him a cop. But I already have a cop in my last manuscript. Then I got to thinking... is it alright to go with the same occupation for my characters? I tend to go with artists a lot. My heroine in Sweet Forever is an artist and innkeeper. My hero in Storm Within (my novella) is an artist. In my current wip (tentatively titled The Staying Kind) the heroine is, yah, you guessed it... an artist. My heros have been fireman and a cop (I looooove a man in uniform *drool*), a rancher and a lawyer/senator to be. So a fifth grade teacher would be okay, but I'd like for him to be in a position to help her with her problems, which include trying to find out if her husband and daughter actually did die in a boating accident two years previous.

Okay, time to get ready for work. I'll mull this around and try to come up with some conclusion.
