If you hold exec board offices EVERY SEMESTER from the time you initiate till the time you graduate, yes, you're going to burn out and not want to hear a thing about sorority by your senior year.
I think the problem comes with "well, Sally's already been on exec board...we can hardly ask her to be something lower like the Greek Week chair." Maybe Sally was great for rush chair when she was a sophomore....maybe 1) that is the only exec office she's a good fit for and 2) maybe her circumstances change. I mean, if ex-Presidents of the US can go back to practicing law I think our sororities can handle something similar.
