I agree with Mai: there are no guaranteed paychecks. Whatever field you choose, you will be competing for jobs and will need to be as good as you can be. If you're heart's not in it, it's much harder to be great at it for the long run. If you love it, you're more likely to work at getting better and better at it. Cosmetology is a skill that you can take almost anywhere in the world and find work. It can't be outsourced to a cheaper provider in another state or country. And while the day may come when it may be automated, I don't think anyone is going to be sticking their head in a hair-styling robot anytime soon. Your skills, talent, and determination will likely determine whether you work at a walk-in chain or own your own salon/spa. It's not easy by any means, but neither is archictecture.
