The fact he managed to come back from losing his sight and still live an extorordinary life is astonishing. He became the first blind man to walk to the South Pole.
Sadly, Mark's story did not end here. In 2010 Mark fell out of a second story window and became paralised from the waist down.
Contary to all expectations, Mark bounced back again. He now gives inserational speeches to business people about how he handled the challanges that had been given to him. one of his main messages is that in life, there are always challenges. Some of these challanges are things you choose but others, choose you. Mark's ability to accept the reaility of his disabilities and make the most of what life he has is truely amazing. If you are ever stuggling withanything you can just think of what mark has had to cope with and then things wont seem so bad in comparison.
I feel very privalaged to have heard this man tell his story first hand.
