If you have some specific condition like Asperger’s Syndrome or a physical disability there is no need to let it destroy your life. There was a wonderful quote somewhere (I’d attribute it if my memory wasn’t going!) about the contributions made by Lord Nelson, Winston Churchill or Stephen Hawkins (one half-blind, one depressed, one completely disabled).
We could all just be sorry for you but it’s much better if you just tackle the difficulties and you start by understanding your condition. Use the internet to find out what your condition is and what limitations it imposes on you. Then pick those activities that you can do.
Almost everyone can tackle a job of some description. Taking part in the Paralympics might be setting a high target – but then those who do can be an inspiration to us all. Try this site http://www.paralympics.org.uk
