If you sat and watched me lecture on running, and you understood everything I said 100%, but you weren't actually actively running, would you feel comfortable going out for a 10 mile run on Saturday? How about a 3 mile run?

What if you showed up for my coaching sessions every week, diligently listening to what I said, and running on the track for a half hour a few times a week. Would you be comfortable going out for a 3 or a 10 mile run now?

How about if you put off all your practice until the day before you were going to do the 10 mile run or the 3 mile run. Could you cram all your practice in the day before and have a good 10 mile run? Could you have a good 3 mile run?

Unless you are doing a lot of running on your own, you answered no to all of these questions. You know that in order to do something tough like run 10 miles, or even 3 miles, you have **got to**** practice running** or you won't be able to do it.

**You have to practice math** to be able to do math. To perform at a 3 or 10 mile math event -- an exam or a final -- you have got to be doing some regular extended practice.

This is why teachers assign homework. We are trying to get you that practice.

I want you to succeed, and I know that in order for you to succeed, you are going to have to practice some mathematics.

Just like with running, you are better off spreading out your practice. In math, working problems 30 minutes to 1 hour a day, every day, is better than trying to do everything in one day right before an exam. Besides, if you leave everything for the last minute, where can you go for help?

The students with the highest grades in the class almost always have perfect or near-perfect homework scores. The worst grades in the class inevitably go to students with lackluster (at best) homework scores. Coincidence?

Some people are better at math than others, just like some people run faster than others, and some people need glasses to see while others don't.

But as with most athletic endeavors, the more you practice, the more you can do. In face, there is some truth in the idea that the more you practice math, the smarter you get.

The truth is that most people are capable at being competent at math. Just like most people without serious health issues or disabilities can learn to run 3 or 10 miles.

By the way, I'm no good at running. I'm not talented at it. I'm not fast, and it's not easy. I've still done a half marathon.

The hardest part was **to get started** which required me to believe that **I could do it** and to find **steps I could do** to get me there.

If you will work on the first, believing you can do it, and bring in the motivation to try, I will help you identify the steps to take.

There are also some bad teachers out there. I've heard some horror stories. I've lived through a few horror stories.

You already know that there are a lot of worthwhile things that aren't easy.

In martial arts and Zen philosophy, you'll often hear, "Just chop the wood and carry the water." That's all I want from you: just do work you know you have to do. Do that homework diligently and well. If you are conscientious with today's job, the big picture will come together.

Sometimes it is hard to see what application a given piece of math has in the real world. This is often because we are learning one skill in order to progress to a harder skill.

Most of us learn to crawl before we learn to walk. We needed to have our bodies understand crawling before we were able to have our bodies understand walking. How often do we crawl once we have learned to walk?

Likewise, what is a pushup good for? It is good for building strong muscles.

What is math good for? It is good for building "brain muscles". Logical, clear thinking.

And what is that good for? It is good for increasing your income. More math = More money. Whether or not you see the point right now, chances are good that your wallet will see the point after you graduate.

Do you have a hard time getting started? Does the thought of spending hours on math homework make you want to scream?

Instead of putting everything off to the last minute and struggling with it for hours, try using the 15 Minute Rule. Even you can handle working on math for a measly 15 minutes.

**Ask questions. **And when you get an answer, summarize that answer to the person who explained it to you.

**The smartest student I ever taught** would always say to me,

**Explain to someone else.** This is probably an even better way to learn than doing homework. Every math instructor you will ever meet will tell you that we learned a lot the first time we taught a class.

**Find a friend or a group to study with.** One caveat here: you have to find someone or a group that you actually study with. If you copy someone else's work, that won't help you, no surprise there. Everyone tries each problem, and you help each other out when you are stuck. If you are more motivated by people than by problems (I am), this might really help!

**Take advantage of all the resources at your disposal.** Class, your teacher, math lab, all should be no brainers.

Another resource is Google. What? Isn't that cheating? If you look up a solution, understand it, and cite where you got it, that is **not **cheating. The fact that **you had to work** to get it will help it stick with you.

You might also want to check out Wolfram Alpha.

Now that you understand that problem, **go explain it to someone else!**

XKCD had a funny cartoon on (computer) problem solving ... mouse over the cartoon to get the secret message...

If you have math anxiety, please go visit the Student Counseling Clinic.

If you have repeated, debilitating anxiety, please talk about it to **your personal physician** or visit the Student Medical and Counseling Clinic and emphasize to your physician **that you are in real distress**. Don't tough it out, get help. I've suffered from debilitating anxiety too; it makes it difficult to get through the day and really difficult to do math.
