Producer comes in many different forms and they are to do many different things. My life of a Producer including Project Managing, Product Producing, Product Researching, Team building, Marketing and heaps of other unnamed things.
Being a Producer require lots of skills. They are skills you learn from books and courses, skills you pick up along the way, skills you learn from your own failure. Not everything people can teach you, but lots of things you can observe and learnt from others. Learn how to learn is a very important skill you should be educated before you learn anything else.
