Inspirational speaker Nick Vujicic is in Singapore to spread the message of hope. And true to his motto of "Life Without Limits", Nick - who was born without arms and legs - made a dive with sharks on Thursday afternoon in the Marine Life Park at Resorts World Sentosa. This is Vujicic's seventh visit to Singapore and he is here to share his inspirational life story. The 30-year-old Australian was born without arms and legs - a birth defect he said had no medical reason. Vujicic attempted suicide when he was 10 as he was an easy target for bullies in school but his parents love for him and his faith in Christianity made him realise there is more to life. "I realise now I don't need to be like anyone else. The truth to my value is not determined on how I look, how smart I am, or how many friends I have. I need to be the best me that I can be," said Vujicic. He went on to graduate with a double degree in accounting and financial planning. He was inspired by Philip Toth - a man who despite suffering from a neuro-degenerative illness became an inspiration to other bed-ridden people. Vujicic recalled: "When I met him two years before he went to heaven, I actually saw him and he smiled at me. This huge smile inspired me. I'm like, 'Wow, if this guy can't walk, can't talk, he can go and inspire hundreds and hundreds of people, what am I doing?' There is a greater purpose to my life than just having things, money. "Money can't heal your heart. Money can't give you purpose. I don't want arms and legs, I want purpose. I don't want arms and legs, I want peace. I don't want arms and legs, I want to be a miracle for someone else. And knowing that perspective, he really went all the way. And he was very inspiring to me to really challenge my dreams and to dream a little bit bigger." Today, Vujicic is living his dream, travelling across the globe to give motivational talks. To push his limits further this time, he made a dive in a shark habitat -- his closest encounter so far with the marine creature. "That was an awesome experience. I've never had anything like that before. In fact, looking through the glass, you don't feel like you're in a glass tanks. You feel like you're there swimming with the sharks. It was a really cool experience," he said. He will be addressing a crowd of 5,000 people on September 7.
