I am not a chef or a cook, but I can tell you this..........there are people who know what they want to do while in high school and there are those who do not. There are straight paths and there are paths that take you different directions until you get where you want. If your love is cooking, then you should take that path. Don't worry about what people say...if it's in your heart than do it. You never know what you will create or become as you become that cook.....example....creating a different type of food or cuisine. Asian fusion was something that someone came up with...it's not always been around. The sky is the limit when you have the passion to do it!
Hope that helps!
