Aside from buying more gear because it's new and shiny lol
I'm having something on an overhaul as I'm mostly self taught. I've been using Justin's awesome site to work on the basics and I'm tempted to buy some of his song books too.
I can tell you everything I know about music theory and sight.reading in one word.....nothing. So they're priorities. I'll be brushing up on ear training too.
Taking regular breaks to drool over new gear obviously lol
