Why are you going to go to a culinary school to learn how to cook? Granted, Culinary schools do give you a slight edge (very slight) The only reason why I say that is there are a few minor certifications that you get with the criculum. They are easliy attainable on your own. On the job experience is the only way to make it in the restaurant world. If you just want to be a line cook thats fine. If you want to have your own place here is the best adivse that I can offer you both old and young! GET A BA DEGREE OR HIGHER IN BUSINESS AND MAJOR IN MARKETING!
The mastery of kitchen work does not make a successfull restaurant. It is the numbers, location, and marketing that make the restaurant go! Now, you do have to use common knowledge in running a kitchen. This is where experience comes into play, use someone elses resources and endeavours (dreams) to fuel your passion. in other words gain as much experience as you can before you swim on your own.
In my own thoughts, Culinary Arts Schools are for general people who want to go play home economics for a few hours a day! Dont waste your time and hard earned money!
