Welcome to Steemit! You play guitar very well, and it's great that music and practical skills are forming a foundation for your quest for knowledge. So many kids just get plopped in front of a television, or spend their day texting, to the sad end of their curiosity.
That you have written a book is admirable! I am pretty confident that if you serialize it and post chapters on Steemit, you'll be surprised at how well it is received.
I wrote stories for my kids, when I homeschooled, and it was always something unique we shared and enjoyed.
Thanks!
