You have done me a great honor in inviting as as your Commencement Speaker on this very important occasion — your graduation day, in this very prestigious university.
Your university and its noble task of promoting education played a great part, and continue to do so, in charting the fate of our nation through the graduates that it produces each year. And its goal of advancing such tasks has not wavered.
The University honed you to become a globally competitive talent and at the same time molded you as men and women who would make our country proud wherever they may be in the practice of their profession.
