Rarely Asked Questions

These are questions I've been asked only once or twice, but which were thought-provoking enough that I want to post them anyways. To give credit where credit is due, this idea was stolen from Paul Graham.


How did/do you have so much time?

Mostly by cutting out activities that aren't important to me.

I feel high school students tend to focus too much on "local" changes (using Chrome productivity extensions, shaving time off X, etc.) than on "global" changes (dropping entire classes or commitments). It's not that local changes are bad, but you should usually consider global changes first before local changes (80-20 rule). Aggressively dropping classes and extracurriculars that aren't adding value to your life are good examples that I think people don't do enough.

I took this to extreme measures in high school. As a senior I took a total of 2 HS classes (not AP) and spent on the order of 30 minutes on homework per week; as a result I had enough time to do math, write a geometry textbook, take graduate math classes, learn to play this piece, sleep a ton, AND play StarCraft. While I don't encourage everyone to do this, I think it illustrates my point.

In general, I think most high schoolers don't spend enough time thinking about exactly what's important to them; this is understandable, since it's an error of omission, and so you make such errors by default. It's especially bad in high school because high school gives you a very clear path of "this is what you should do" by having you go to class every weekday until 3PM, then assigning you the homework to do at home, and giving you letters of the alphabet which amount to obedience scores. But school is rarely optimized for the top students (even at magnet schools), which is why I had the guts to tear up my entire default schedule and replace it with the things I mentioned before.

For those of you who were at Math Prize 2015, Victoria Xia made a somewhat similar point at this year's MPFG Alumni address, which you can watch here, 49:30 -- 55:30.

What's the most important thing that math contests taught you?

In my opinion, one of the most damaging messages I got during high school is that hard work pays off. This is not true, and one of the most important life skills that math contests taught me were how to work hard even being fully aware that I might never "succeed".

In school there's a mentality that teachers should reward "good effort", i.e. if a student tried their best, they should get a grade of A. By extension: "if you work hard in life, you will succeed". This turns out to be quite far from the truth. Math contests teach you this lesson much better: you can love the subject, work harder than everyone else, do everything right, and still not win the USAMO: that's what makes it worth doing. Statistically, almost no one wins the USAMO, and that's why winning (or "losing") the USAMO is a meaningful experience.

To quote Paul Graham:

Hard means worry: if you're not worrying that something you're making will come out badly, or that you won't be able to understand something you're studying, then it isn't hard enough. There has to be suspense.

You don't see faces much happier than people winning gold medals. And you know why they're so happy? Relief.

This is why I think of high school (and college) as "fake" while I think of math contests as "real". Anyone can work hard if reward is certain, but in real life this is simply not the case.

With all that being said, I am obliged to add on that the other huge thing that contests did for me was provide me access to one of the best peer groups out there. Most of the friends that I have today came in some way or other from the math contest circuit, even though many of them will certainly not be doing math as a career. (This doesn't technically relate to the question because it's not something I was "taught", but it would have been dishonest of me to omit it; the social aspect of contests was huge for me.)


How do you stay motivated and work hard knowing you might fail?

I would have worked on math contests even if there was no USAMO for me to do well on. Proof: I'm currently a college student and I still work on contest problems in my spare time.

Therefore, my advice is to worry about the outcome as little as you can get away with. You should probably put some planning into the final result rather than being totally aimless, but it's quite easy to overdo this; too often it becomes type-B procrastination. This is why it's so important in anything to enjoy the process itself: time spent thinking about the final result is time spent not working towards it.

This is even true during the USAMO, for example. You can't afford to spend much of that time worrying about your score. It's true that score considerations can be helpful to some extent (for example, know to cut your losses on Problem 2 and move on to Problem 3). But it's quite common to see students who are so nervous about their score that they end up underperforming. This is clearly a losing situation.


Would it help to have a tutor/mentor for olympiad math?

Short answer: yes, but not in the ways people often expect. Long answer: this blog post.
