I think Dr. Kalam itself is a good example to describe meaning of dedication, sincerity, confidence -encouragement. Please read book written on him like "Wings of fire", "The Kalam effect" for reference. Its all about his dedication to learn, to acquire knowledge, to make the nation proud -sincerity toward his job doesn't matter as a Prof. or Scientist or President of India. Confidence : to serve as Democrat to lead in front for the nation however he spends his whole life as educationist/scientist.
........I believe, If he doesn't have such high qualities -the facilities and limitations, he faced in his early childhood may not allow him to make his own destiny.
But if we leave everything on individual abilities-we cannot produce quality in mass whether we have that potential. Specially if we are thinking to make our Nation No. 1 in the world.
There are so many people in our education system who have the ability to deliver their excellence and quality but are discouraged to do so by few people who are interested in getting higher positions, making money ...things like that, instead to encourage and promote education to higher level. Such few people are like a fish in pond who are only alive to make dirt in society at any level.
