Want to make money? Sure you do. Who doesn't? Jim Cramer, host of CNBC's “Mad Money with Jim Cramer,” knows how to make money by investing wisely, and he tells the rest of us how in his new book. Here's an excerpt from “Jim Cramer's Stay Mad for Life!”

Introduction: Get rich and stay rich
Most people don't think about it, but there's a difference between making a lot of money and building lasting wealth.

When it comes to money we think that striking it rich is the ultimate goal. I know because I used to feel that way. In reality, getting rich isn't the financial finish line. It's the first lap of a much longer race.

I'm talking about ensuring long-term prosperity for you and your family: not just getting rich, but staying rich. That's what each and every one of us truly wants to achieve with our money, and I don't care who you are, who your parents are, where you live, or what you do for a living: you can do it if you let me help you.

I don't care if you don't have two cents to your name or if you owe thousands of dollars in credit card debt. I am confident that I can get you there. You may think of yourself as someone who's awful with money; you could be a person who's tried and failed to get anywhere with every single financial plan you've ever been handed, like so many faddish diets. Whether you're 16 or 60, sending your kids to college or sending yourself to college, I'm writing this book to tell you everything you will ever need to know and everything you must do to create and maintain the kind of wealth that lasts a lifetime. I want you to get there and stay there.

A lot of people who try to sell you advice about your money are doing it to make money themselves. They don’t care whether you succeed or fail with their advice because they're just looking to sell books or earn fees. I made more money than anyone ever needs working at my old hedge fund, and if I wanted more, I'd start another one. I am confident that I could raise a billion dollars to manage tomorrow, but frankly, I'd rather help you.

That means more to me than working for people who are already rich. Perhaps it's because I'm a good guy, or because I just want to look like a good guy, or maybe I do it because I love positive attention. Maybe it's because after years of making money for myself, it just feels right. At the end of the day, the “why” isn't important, as long as you're satisfied that I'm writing this book in good faith to help you. What's important is the “what.” I spent fourteen years running a hedge fund, which means that the only higher purpose my job had was to make incredibly rich people even richer. I used to joke that my job was to move people higher on the Forbes 400 richest people list — not a higher calling.

I've now spent the past seven years since I retired from the fund writing books and columns for TheStreet.com and New York magazine and hosting a radio show and two television shows: first Kudlow & Cramer, then Mad Money. The venues have changed, but my goal was always the same: to share my experience and expertise with regular people to help them become rich. In this book, I'm aiming even higher than that: I'm teaching you how to make money and use it to ensure enduring prosperity and permanent financial security over the course of your entire life. The disciplines and the knowledge you need to build a firm foundation for your wealth and maintain it for the rest of your life are not the same as the ones you would need to make yourself rich by investing in stocks, the subject of my previous two books. If you're looking for long-term financial security, I would hope you'd set your sights higher. For long-term extravagant wealth, you need to know how to take advantage of tax-favored vehicles like 401(k) plans and IRAs; you need to know when you should buy bonds rather than stocks, not to mention the kinds of bonds you should choose; you need to know how to save for college; how to guarantee you have a smooth retirement; how to save; how to borrow; when you should buy a house; when you should be taking risks; when you should be avoiding risks; what you must teach your children about money; which mutual funds you should put your money in; and which stocks will look good for the long haul, the next twenty-five years. These are the subjects people beg me to address, and I am ready and willing to do so. I have the answers for all of the financial questions you, your parents, and your kids have about getting rich and staying rich.  Don't be intimidated — I'll explain everything in layman's terms, not in the Wall Street gibberish the professionals use to scare you into relying on them instead of using your own judgment.

But what about my judgment? You want to know where my advice comes from, and I don't blame you. Most of what I know about making money I learned in my years on Wall Street, first as a broker at Goldman Sachs, advising the wealthiest of the wealthy about all these lifetime issues, and then as the manager of my own hedge fund, Cramer, Berkowitz & Company. I've had a long love affair with stocks, but stocks are only one of many tools, albeit the most important one, that we're going to use to create lasting prosperity for you and your family. I know better than most people the difference between having money and not having it, or having it and having a whole lot of it. I'm a self-made multimillionaire, and I'm going to share with you the lifelong disciplines that made me rich and have kept me that way.

As I said, I made my own money. I've also been poor. In fact, I wasn't just poor; I was homeless and destitute. In 1978 I spent six months living in the backseat of my Ford Fairmont while I worked as a homicide reporter for the Los Angeles Herald Examiner, unable to afford even rent money. By 1979 I had moved up in the world; I was living in the most spacious corner of my big sister's studio apartment in New York City. I was the last person in the world anyone was ever going to ask for financial advice, but even then I was diligent and self-disciplined about money.

I may have skimped on the auto insurance and skipped on the rent, but I still put $50 a month into the best mutual fund I could find, Fidelity's Magellan Fund. I have always been fascinated with mutual funds and managers, and I am going to tell you all about which ones you need and which ones you should avoid. I know what it's like to need money and not have it, and ever since those early days I have lived in desperate fear of poverty. Living out of my car with barely enough money to get by convinced me that I had to become rich, that no amount of money was too much, and that I would have to do it with more than just my meager paycheck. I would have to parlay that paycheck into something much bigger, using whatever financial resources I could get my hands on. I spent twenty years single-mindedly pursuing greater and greater sums of money until well past the point where more money made a bit of difference. I know it's possible for anyone to get rich and stay rich because I did it myself and I'm no different from any of you.

Like most things in life, getting rich and staying that way take a lot of hard work, a lot of knowledge, and a little bit of good advice. There are many ways to get your hands on a whole lot of money, though few of them can be called easy. You can invest in the right stocks, get a high-paying job, start your own business, or inherit the money, to name just a few. But there's only one way to make sure your new-found wealth leads to long-term prosperity: you have to use your money to make more money, and you need to do it the right way. It's hard work, and it takes diligence, but in this book I've already done a lot of the work for you. No, I don't have six easy steps to financial security, nor do I have three magic habits that will make you a millionaire, and I can't tell you the financial secrets of the superrich because as far as I know, they're just as feckless with money as ordinary people.
