Wow, you sound way too busy there! I'm brand new at this instrument playing so am hardly one to be giving advice, but I can't imagine trying to accomplish anything while faced with an array of instruments that you just listed. My compliments for even trying. While playing a guitar is new to me, I have other endeavors that I have become relatively accomplished at over the years. Each of these has taken an extreme focus and I focused on only one interest at a time. Whether it was as a pilot, tournament chess, Texas holdem, tournament poker or bullseye pistol competition, each of these took several years of dedicated, extreme focus to develop the skill set necessary to be as good as I wanted. I no longer fly, compete in chess or pistol competition due to age and a few minor health issues so have decided to expand my focus to something to warm my soul and keep my brain in an exercise mode. It is tough, but after only 3 weeks of focused practice I can see progress. MY fingers hurt like hell and are developing callouses...guess that's a good thing. Anyway, good luck on your journey. Why not put the rest of those musical toys in the closet, lock the door, and focus the the guitar? Good luck, and I'll bet that the talent your father demonstated is there inside you waiting to come out. I'll also bet that he put in a number of years focused on his art. BY the way, I started private lessons once a week, 3 weeks ago. Had my third lesson yesterday and having a good instructor is a huge help....he/she can correct any bad habits before they become engrained
And push you to be all that you can be.
Good luck!
