At 14, you must be in about 9 or 10th grade, I'd guess. I don't know what state you live in, but I would try to get a part time job working in a restaurant. This is what I did in my high school years. Worked nights after school, and sometimes weekend days and sometimes weekend nights.
I'll guess you're already taking home economics or classes that involve cooking.
College is a chance to find yourself. With time and learning, your views will change and things will tend to become more focused. You might find that you want to become involved in food chemistry, or micro biology which plays a big role in modern food processing, or decide to use your college years to emphasize your sense of business management and perhaps skills in political science. Try to take classes in all sorts of areas. Maybe some music education or history, some physics and math, some humanities, philosophy, all kind of things. The more broadly you expose yourself during these upcoming years, the more rounded and in perspective your life and dreams will become.
Then, with all that college behind you, you will be much better positioned to make the decision to go to culinary school or not.
Just my thoughts and good luck to you!
