Try a different instructor and don't do it part 141. Or go drop bodies at the local DZ. dropzone.com check out the employment section.
My only caution to that is that you're going to get a whole lot of day VFR time, and the IFR, night and cross country time can be very lacking. A coworker of mine left our school to do banner towing for about 1000 hours. He came back, got his CFI, and is instructing. It has really hurt his career opportunities as he has over 1500 hours with not enough night, cross country, or instrument time.

@ChasenSFO said though, don't teach if you don't want to do it. The students deserve someone who at least has enough drive to teach for the student than to just teach to build flight time.
I will say though with the flight instructing certificates, you become a lot more knowledgeable because you realize just how much you really didn't know that you thought you did when you start having to teach it all to someone else.
I have a friend who flies a lot of corporate such as Lears, Citations, King Airs etc. He has told me if he was looking to hire someone himself, he wouldn't hire anyone who didn't have their instructor certificates. Now that will vary person to person, but being a flight instructor is definitely a huge resume booster, and character builder in a lot of ways. I certainly don't regret my time being a flight instructor, and I feel better off for the experience.
If you don't do your CFI, try to avoid doing 1000 hours of dropping bodies, or towing banners unless that's all you plan on doing with your career, or you don't mind a delay in finding that 135 or 121 job you really want.
