Vedanta Resources Founder and Chairman Anil Agarwal said he won't retire soon and added the conglomerate's growth requires his "aggression" and "risk-taking" ability. "Why should I hang [my boots]. I have a task [to finish]," he said. "Nobody can think of producing [5,00,000] barrels oil in such a short time... you [must] take the bull by the horn," he added.
