“It’s true that as a young undergraduate student, there’s ample room for experimentation. However, it’s more advisable to experiment purposefully. You could think that if I’m proficient in mathematics, then I could spend a summer doing research, and if academia doesn’t suit me, perhaps I could combine the math skill with a few courses in computer science to be a specialist in artificial intelligence (deep learning). Do you see how the experimentation is based on an assessment of your strength, and arranged with a fail-safe plan? I haven’t had much planning until I started working, but I know had I planned properly, I could have gone further in my career. Planning and experimenting are not mutually exclusive. In fact, they are complementary to each other.”
