if it's installation, much can be learned at any of the installer institutes. If you are concidering opening your own shop, you better have a general business degree and someone with a hellofalot of capital for the initial investment.
But the guy above was right, in this hobby you either have it or you don't. Some people don't have the vision of what it takes to make something. They look at a box and only see a box, they don't see all the intricate details it takes to get a sheet of MDF into the box. I have had the pleasure of being able to work with some truly gifted installers, and they are a totally different type of person. They have vision...not just ideas.
