Experience can not slowly accumulate, slowly learn, such as opening a restaurant, as long as you find a trusted and experienced teacher on the line, (preferably introduced by a relative or friend) so that he is the manager of the restaurant's daily operation of the matter to teach him to be fully responsible for you to do shareholders, take the dividends on the good, and at the same time, to the restaurant to work, to do what they can do, and learn by doing.
If you don't have the financial strength, you are a college student after all, probably more than mom's money, you'd better go to work, since mom just got laid off at 44, let her rest for a while. Since you are afraid of mom looking for a job to be angry, more part-time job is good, you have to work a little harder. For example, if you work Monday through Friday, you can work at a fast food restaurant as an hourly laborer on weekends. Just an analogy, as for what you can do, but also depends on your own skills.
