Success story Dr. APJ Abdul Kalam

From selling newspapers to becoming the President of India, Dr. APJ Abdul Kalam undertook a long journey, but what made him reach his destination was the fact that he never let his spirit waver. He didn't give up on the dreams of that little boy who studied under kerosene lamps and kept working towards his goals.
What is an inspirational story about APJ Abdul Kalam?
Kalam tried his best to make an aeronautical design for aircraft in a lab-class. But his teacher rejected the design and gave him three days to design it again in order to contain the scholarship that he had received. Dr. Kalam worked incessantly and made it again.
He was awarded the Padma Bhushan and Bharat Ratna, and then he became the President of India; one of the few presidents who have touched the hearts of so many poor children in the country. Because he also came from a poor background, he knew the power of education in changing one's future.
