All investing success requires mastery of a single skill.

If you don’t gain this expertise, you’ll never make much money as an investor. You might occasionally get lucky… but you’ll likely lose everything you make without this skill firmly under your belt.

The skill I’m talking about is saving money.

But it goes even deeper than that…

Few people realize saving money is more than just accumulating capital. Saving instills a discipline that touches everything you do with money for the rest of your life…

And it’s all due to a certain way of thinking.

Today, I’ll focus on this specific way of thinking, and why it’s so important. It’s a secret almost nobody else will tell you…

Saving money means not spending it. The skill is negatively defined.

Negative advice is an extremely important part of what we do in my Extreme Value newsletter.

To understand why, read this quote from trader and philosopher Nassim Taleb’s must-read book, Antifragile…

Charlatans are recognizable in that they will give you positive advice, and only positive advice… Yet in practice it is the negative that’s used by the pros, those selected by evolution… people become rich by not going bust (particularly when others do).

Great investors routinely define the core of their investment strategies by what not to do, what they don’t know, or by stumbling through mistakes, rather than marching from one success to another.

Here’s some of the best negative advice from the world’s greatest investors…

Saying “yes” to growing wealth means saying “no” to mistakes, disasters, and losses.

Investors don’t pay enough attention to surviving disaster – to not going broke, another negative skill. Instead, investors overwhelmingly favor positive advice and risky, speculative stocks.

I want to be like the rustic who said he just wants to know where he’ll die so he can avoid ever going there (a quote often related by Charlie Munger). His whole life is focused on the primary negative he wants to avoid.

Taleb sums it up best: “The learning of life is about what to avoid.”

Besides saving money and avoiding disasters, many other negative skills trump positive advice. For example, holding stocks long term as they compound your capital might best be defined as not selling every time the market hiccups. Not paying high fees and trading costs is another important negative skill.

It’s unlikely you’ve heard much, if any, explicit discussion of the primary importance of heeding negative advice. Taleb is the only financial writer I can name who has explicitly developed the idea.

Negative advice isn’t popular. It doesn’t sell books, magazines, brokerage services, financial planning, trading software, financial cruises, mining stocks, gold coins, asset management, mutual funds, or exchange-traded funds. And it certainly doesn’t sell newsletters.

But you can ignore it at your peril…

For example, in the April 2008 issue of Extreme Value, I warned investors that the housing bust would result in multiple bank closures. I said it would be much worse than most people believed at that time.

You know what happened next… The S&P 500 Index fell nearly 60% from peak to trough. Extreme Value subscribers made 82% in five months on our recommendation to short shares of investment bank Lehman Brothers.

By focusing on negative advice, you can learn to “see around corners”… so that big financial disasters are less likely to jump out suddenly and blindside you.

In short, you can’t be a great investor without mastering negative skills.

It’s the foundation of everything you’ll do right as an investor. You can’t invest at all without it… And the better you are at it, the better you’ll be at other essential investment skills.

Good investing,
