Advertising, catalogue, & fashion for the most part. On the side photojournalism and Sports photography. One thing I learned was it takes time and practice to learn what you want to learn. The first thing you have to do is learn light and the properties of light. That takes time and effort to accomplish because it is as much science as anything.
When I asked you early on about angles it was simple geometry. A simple way to learn practical geometry is play Billiards. Me I prefer carom or three cushion billiards. You learn the physics and geometry much quicker than say pocket billiards.
Once you understand light you can use the same geometry it takes to make a successful billiards shot to set lights.
