Should I go back to doing hair?

I have a dilemma. I quit doing hair and am in college. I currently have 2 years left to finish, but I have to work while attending school to support myself. I never made decent money as a hair stylist. I enjoy people, but I like quiet time and I am more introverted than extroverted. I don't like standing/sitting around waiting on clients and I feel uncomfortable pushing clients to come see me. I know marketing yourself is part of being a stylist, but a part of me feels pushy doing it. I always had a problem handing out business cards to random people like we were told do in beauty school.

For the past year I have been working at a department within my university's offices, but the budget does not allow for my contract to be renewed on a full time basis, so my hours will be vastly cut.

I am considering going back to hair, but I feel very apprehensive. I have been told by family members I should just do hair for my career because it will give me the potential to make a lot of money and freedom. I feel frustrated because it feels like no one understands! You can't just walk into a salon and start making even enough money to live off of to support yourself. I had to struggle SO BADLY and I hate the memories that I have of working in a salon. The fun moments that I had cutting hair sometimes just didn't outweigh the bad experiences and the struggle.

Can anyone relate? I am so torn. I don't want to be at the mercy of an employer for the rest of my life, but the salon industry feels over saturated with hair stylists.
