"Today the world is looking for solutions, and you have the potential to provide them. There is infinite opportunity in India today. I urge all of you here to give yourselves a chance to be fearless. Work on your ideas. Dream big, think differently, and be fearless," he said in Chennai while participating in the golden jubilee celebrations of Jaigopal Garodia Hindu Vidyalaya Matriculation Higher Secondary School.
