Dr Kalam continues to live in the imagination of the people of this nation and remains a role model for the youth and missile and space scientists who are diligently following his vision to achieve new laurels for India, notes S M Khan, who served as President Kalam's press secretary.

'President Kalam would always say -- this was one of his pet sentences -- that "If you don't do anything, there will be no difficulties but if you do things, there will be difficulties. You have to overcome them. Don't be afraid of difficulties".'
