He started a business during university days

SMU psychology graduate Clement Wong was featured in an article. He took a six-month leave of absence from his studies at SMU to start a social media consultancy, which has recently been sold. The consultancy, set up in his second year at university, gave him the income he needed to pay off his study loan. He said that Ms Pamela Lim, a former corporate high-flyer who was an entrepreneurship and innovation senior lecturer at SMU, encouraged him to consider starting his own business. He also shared his experience in investing.
