On studying mathematics
> I understand that most of us do not have a good experience when studying mathematics in high school or college. I assure you that this is a common problem, not only in Vietnam, but all over the world. Mathematics is taught and learned mechanically, without joy. But don’t worry, and please be optimistic, school is not the only place we can learn. I have never had a college degree, and if I can study math, anyone can learn it. The only thing we need is an open mind, daring to try new things, the rest can be left to math!
