should i study automotive engineering or just go to mechanic school
      Answer1:Neither will help you. Youre not going to be a mechanic. Youre going to run a store. To run a store, it will help you to take business courses. I would suggest you get your BS in Accounting, and your Masters in Business (MBA). While getting the BS, you might also consider getting a minor in Human Resources (i.e. this will help you in managing your employees).
      Answer2:There is a site that has a bunch of information on business given from industry experts and other successful entrepreneurs. If they dont have it they will try to help you find the information you are looking for. We use it at my college it wont let me put a link but search: Business Empire Magazine
