Oh my, I can imagine it has. I think you will be surprised what you can do. They told me I would never walk again, but I do. They told me I could never have children, but my son will soon be 38. I thought I would never write again, or make graphics because of my vision problems, but I have taught myself to understand what colors I see, compared to the colors everyone else sees. I guess I am trying to say that every time something pops up in front of you that appears you can't do it, just don't give up until you figure out a way to do it. Don't worry if its not pretty or perfect. As long as it gets the job done, don't worry about what someone else thinks of it and you will be surprised what you can do.
