Everyone I know who is successful has issues with their father, regardless of whether it was sports or business or entertainment.
II know very, very little about the ukulele, but I actually grew up playing the viola from 4th grade through high school.
I much prefer working with kids whose life could be completely upended by a reading of a book over a weekend. You give them a book to read - they go home and come back a changed person. And that is so much more interesting and exciting.
