I have a hobby and talent of public speaking. I have also had a lifelong fantasy of being a ballerina and I took classes as a child and was quite good esp. What are you trying to accomplish by publishing so many materials in void. If you love music but have a full-time job in another field, you may enjoy a side hustle that allows you to make some money from your hobby. I have spent thousands of dollars on college classes over the years trying to find something that might interest me, but that led no where other than adding hundreds of credits to my record. Still, if you have a real talent for it, you can rise above the competition and make money at it.
