If possible, I would continue working as a multimedia developer, but my photography and video work would probably end, or drastically change. It would depend on how much was paralyzed.
One area I could continue working with is training development. As long as I have my eyes, my voice and my mind, I can continue to develop and train others. I would just have to rely on others to do a lot of what I do now.
One big change would be how much I rely on others. I am currently a very independent person who would rather do it myself and get exactly what I picture in my head. With the loss of mobility and other capabilities, I would have to stop being so stubborn and learn to lean on others. Actually, I should start doing that now.
