Thank you both for your prompt response. As I am sure you gathered, I am an amateur always trying to increase my knowledge. In my day job, I sometimes have clients who want to hover as I work. I usually do not allow it because it produces errors and poor work. That might be one of the differences between business and art which is another thing I am struggling to deal with.
I do want you to know how much I like the videos. I have always purchased books believing that I would learn more and access the knowledge better with a printed book. Your videos have opened a new door for me. They flow so well and present answers I retain so I do not need to have a book to refer to.
