Dravid answers

Cricinfo:

What motivated him still, after all these years and so many runs? Dravid said that as a schoolboy, he remembered many kids who had at least as much desire to play professional cricket as he did - they attended every camp and net session, no matter what the cost or the difficulty of getting there. But you could tell - from just one ball bowled or one shot played - that they simply didn't have the talent to make it. He knew he was different. "I was given a talent to play cricket," Dravid explained. "I don't know why I was given it. But I was. I owe it to all those who wish it had been them to give of my best, every day."

He succeeded brilliantly.
