Hey Dave!
As it happens, my brother Is an electrical engineer. Your post reminds me of him a bit. As busy as life will permit, yet still wanting to do more (the guitar being one thing)
The great thing about guitar though, is that you can play it anywhere any time. Its not like you absolutely have to be at X place at X time to practice. Just grab it out of the back seat when your on a lunch break or have 10 minutes to spare…. At least that’s what I try tell my brother :p
I hope you enjoy yourself here at IG. Keep us posted on your progress.
Mike.
