I won't comment at length, but I will say that I do not think you should believe, "I never got anything out my Chef Training course". Education is never wasted if we do not allow it to be wasted. You have mentioned business management, art and writing. Add that to chef training and I see a lot of opportunity there. And at the very least you should know how to prepare a lovely meal to entertain and influence people on a micro level. I've found your choices to be interesting. Keep trying to reduce your social anxiety; it can be done if you put effort into it.
