I occasionally take breaks from practice and playing when life gets hectic. But as things slow down I always find myself picking up one of my guitars and fiddling on the couch while watch a movie with the wife. Then the next day or so I will be excited to come home from work and practice. I would say the thing that drives me to learn the guitar is my parents didn't have hobbies. They were hard working people but never had any hobbies. I have always loved music and wanted a hobby that will last until old age as well as be able to pass down to my kids.
