Congratulations on your approaching the age for geezer club status. I will send you an invitation when you actually get there.
I commend you on your ability to recognize what you can and can't do with video tapes. Many students, when first starting, think they can learn everything from a video. Your private instructions have helped you to recognize that is not true. As you learn more of the basic techniques from private instruction, you will find that adding a step pattern from a video tape is pretty easy. Adding technique learned from a video tape is not so easy. And of course, correcting those funny quirks that all beginners have that they don't realize, is impossible to do without outside help.
If you haven't started to do this already, I would recommend that you also keep a notebook describing everything you learned in your private lessons. This will help a lot in committing that information firmly into memory, and it also serves as a tool to make sure you understand it. It you can't describe it in words, chances are you don't understand it. It also serves as a good reference for later use.
