learn drums!
decades ago, my husband and a buddy both played guitar, but they could never find a drummer. finally the buddy decided to learn drums, and he got really good, particularly for fast, loud stuff like punk and death metal, but played other stuff, too.
i played e-drums for a while, starting out with simple rock, rudiments and limb independence exercises. it's lots of fun.
