I use Trello to keep track of things, songs, lessons etc I'm working on.[br]I have different lists for songs in my "repertoire", songs I'm just learning, songs I'd like to learn etc.
I also try to do something similar for lessons though don't use it as much as I don't tend to come back to individual lessons as often.[br][br]The nice thing about Trello cards, is that you can add notes, comments, links to the performance backing track lessons in GT, links to YouTube versions of the song to play along with etc, and then move cards between lists as a song goes from being in your "still learning" list to your "performance level repertoire" list.[br][br]I also move songs to the top of the list after I've played them, so I know which songs I've played/practiced recently and which songs I should show some love to.
