Physical Challenge didn't stop him
About Nick Vujicic(From Wiki) Nicholas James Vujicic (born 4 December 1982) is a Serbian Australian evangelist and motivational speaker born with tetra-amelia syndrome, a rare disorder characterised by the absence of all four limbs. As a child, he struggled mentally and emotionally as well as physically, but eventually came to terms with his disability and, at the age of seventeen, started his own non-profit organisation, Life Without Limbs. Vujicic presents motivational speeches worldwide, on life with a disability, hope and finding meaning in life. He also speaks about his belief that God can use any willing heart to do his work and that God is big enough to overcome any and all disabilities.
Although he is physically challenged with his strong will, determination and faith he did over come the physical challenge with mental strength and became most successful in life than an ordinary person.
He focused mind on what he could rather what he don't have. He shifted thoughts to POSSIBILITIES from negative to positive. Instead of thinking WHY IT CAN'T BE DONE, HE THINK HOW IT CAN BE DONE?
