Need help deciding a college major.?

I am a 2nd year college student at the University of Houston. Last spring I recently decided to go into Education, to teach elementary school. However, I got a job as a teaching assistant at a daycare and the job gave me second thoughts about being a teacher. They say that I'm too nice to the kids and the kids won't listen to me. I am deciding on changing my major again.
Going into college I wanted to major in optometry/biology. After I took a biology class, I realized that I couldn't catch up with the stuff, and it didn't interest me.
My parents do want me to go into the medical field though.
I am currently thinking about nursing.
So if anyone could give me some feedback, thanks.

Absolutely: go to the U. of Houston's career development office. They have the tools to assess your interests and talents and to recommend careers that fit your style and skills. Then they can tell you what to major in, as well as what the projected demand and salary would be for the professions on your list.

The advice they can give you is FAR superior to anything you'll get from us anonymous Yahoo!s.

alot of people in my fmaily are nurses considering your situation i believe for you being a nurse is the best way to go.

I want to be an orthodontist
That might be fun
or at least I think so

Try engineering, it's fun.

If you didn't like the job, then it's good that you're reconsidering now, and I agree that your school's career center will be a much bigger help than us. But if it was your first real teaching job, keep in mind that most people don't get a good disciplinary balance right on the first try. It could be just as much your bosses' fault for not giving you proper guidance as yours.
