You should learn to make good gumbo and Mac n cheese for sure. Persian food is great, like Mediterranean meets Indian, lots of good spices and sauces, I have cooked a couple Persian weddings and I would love to learn more dishes from that region. I would suggest learning to make some different sausages. The first sausage I learned to make was merguez and I wish I still had the recipe for that one. Sausage is one of those things that most cultures have because everyone needs an outlet for their scrap meat and fat and why not grind it up and shove it in some intestines? I would start on your own continent and work your way around the world. 

@chefdaddy @chef @mickdawg75 these all sound very good! I think because I loved Greek food so much I'll start off with Persian cuisine and maybe do a few sausages then. Creole cuisine sounds very interesting as well and I'll be sure to do some research :)
