I like to say that the biggest room around is the room for improvement. Most anyone seriously engaged with doing music wants to improve themselves, and working on Musicianship skills is a great way to do so. Fortunately, there are many ways to develop your Musicianship, from taking classes or studying on your own, to collaborating with others, learning Music Theory, practicing reading on your instrument, and other time-tested skill-building activities.
Specifically, anything you can do to improve your technique, improve your ear, expand your repertoire, and practice different styles of music is going to help. Make sure you are clear about your Musicianship goals and how you intend to reach them.
