What was your inspiration to write 'Wings of Fire'?

My inspiration was I have worked with thousands of engineers and staff everywhere. I found two things. Every one can contribute for the nation, if given a properly defined task and demanded. And I have observed that people who did not have proper background of education, by sheer hard work and intelligence they have excelled. So I want to convey human mind is a powerful tool and providing challenge to it leads to blossoming.
