Dr. Kurien defines success not as fame or wealth, but as the ability to contribute meaningfully to society. He believes that a successful life is one where you do your best and uphold values like integrity and humility. Recognition is not the goal; service is. Success, to him, is measured by the good you do for others. He advises his grandson to earn his own rewards through hard work. Personal effort and contribution define a fulfilling life. True success lies in doing your part for the common good.
