"I was recently asked by a journalist at ABLE2UK how I coped with anger and frustration at being disabled. It is a waste of time to be angry about my disability. One has to get on with life, and I haven't done badly.
People won't have time for you, if you are always angry or complaining. It is no good getting furious if you get stuck. What I do, is keep thinking about the problem, but work on something else. Sometimes it is years before I see the way forward. In the case of information loss in black holes, it was 29 years! Due to my illness (Motor Neuron Disease) my expectations were reduced to zero when I was 21. Everything since then has been a bonus."
