I NEED HELP!!!!

My sister has been harping me that i need to go back to school. I don't like school that much, but she said that I won't meet any people by not going to school. Anyway I really want to move to Cedar and she says in order to meet people I should go back to school. The only problem is I don't know what to go to school for. My top pick is Interior Design, but I don't know what I would do with that, maybe I can become the next Candice Olson, for the U.S., I would love that! Or my second choice is Business Management, becuase eventually someday I want to own a fabric store, or a scrapbook store, or a craft store, or maybe even a little botique, maybe all rolled into one. However, my other sister said that wouldn't really help me to have a business degree in order to have a store. I am so confused and I don't know what to do. But another problem is that is if I find a Dental Assisting job i won't be able to go to school. I already have a degree for that and I would really like to do that, but it is a slim chance that i'll find a job in that becuase i really haven't actually worked in an office I only job shadowed. The problem with that is if i do go to school i probably need to figure it out soon so I can apply for it. But i don't want to find a job until i am closer to moving, so i can be here for all the stuff thats going on in my house. I am so confused with my life right now and I have no idea what I want to do with my life. I really need some advice. Any Adive?
