Hey Bill, I would like to learn a new key.  The only key I know is Db/C#. Any other keys you think I should learn first? Any tips on how to become motivated to learn new keys?
if you want to do it, then you're already motivated to do it. if you don't want to, then you don't have to. if you do want to, you can. so it's a win-win there. to decide on a next key to learn, i'd suggest finding the song you are most familiar with that is not in Db. and learn that song, it its original key
