My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit, as well as physically.
I put my career in second place throughout both my marriages and it suffered. I don't regret it. You make choices. If you want a good marriage, you must pay attention to that. If you want to be independent, go ahead. You can't have it all.
Universities are fantastic places to gain knowledge on a subject, develop a personal network, explore your character and learn new techniques to approach problems. I do however believe that there is a strong argument for students who have an idea they are passionate about to just try and turn it into a reality. I fell into this category and I don't regret not going to University.
There were times when I thought I got a bit more punishment than was coming to me, but I don't regret a minute of it now. Each of us must be tempered in some fire. Nobody had more to do with choosing the fire that tempered me than myself, and instead of finding fault with the fire I give thanks that I had the metal to take the temper and hold it.
