Enter Sandman. My dad used to play a lot of Metallica and Foo Fighters during car rides when I was younger, so I spent a lot of late nights learning by myself to impress him. It worked, btw! And as for starting in general, my parents were always big on making sure me and my sister & brother had interests out of school. But I was also a teenage boy in the early 2010s so part of it was definitely just thinking that I would look impossibly cool.
