> Bought a piano and the situation is even more dire.

https://pianowithjonny.com It's awesome :-) I'm playing passable blues riffs and have taught myself to read music with the help of some free apps (Music Tutor on iOS).

There's also a great series of books by Joseph Alexander for the guitar (fretboard fluency, etc). Definitely worth checking out.

For me, the most important thing has always been motivation. Right now I want to be able to walk into a bar/hotel/train station and bash out "Great Balls of Fire" a la Goose in Top Gun. So damned cool... :-D
