Doing mathematics is a long-term thing. I've had graduate students who said, "OK", I'm doing my PhD, and at the end of the four years, I'll have learnt everything I need to know, and I'll be a leader in the field". It doesn't work that way! You have to work through undergraduate, and through graduate, and even after you finish, there is still a lot more to learn. Mathematics is huge. You have to keep pushing yourself and not be content with doing just one or two things and sit in this niche of mathematics and never venture out of it, if you want to really progress. I'd describe it as like running a marathon. You can't just sprint right through it. You have to keep learning, and really enjoy doing mathematics. If you don't enjoy it, you won't have the stamina to keep at it. But it is very rewarding if you keep at it.    ----Terence TaoScience is merely an illusion-A.
