So what does disabilities and art have in commend? Right off the bat most people might say they both are hard roads to take in life, but look on the positive side. Being that I am lucky enough to experience both fields for most of my life, I would say they both have given the gift to solves problems and the ability to see that there is not only one answer.
Everyone might give you their advise about how things should been done, but in the end you adopt the medium or services to best fit your voice/way of life.
This can be seen in artist work, when they find a medium to tell their story, or take a disability service to best help achieve independence.
You might not always reach goodness on your first attempt, but you build on that experience to learn how to improve for the next time.
