Recently I decided to try and learn the bass to help with my concentration and memory as well as to have a calming exercise that might help me through and take my mind off my issues. Unfortunately, avolition is a very chronic problem in my life so I don't get around to practicing as much as I would like to. The intention and the want to use the instrument as a form of self-guided music therapy are there but many times the motivational drive to actually do it is what's missing. But it does help me to take my mind off the world around me and forces me to focus on the task at hand whenever I do play it. So, I guess that's good.
