Do you remember playing pretend when you were little?

Maybe you were a superhero, a dinosaur, or a princess.

It’s normal when you’re little, and it’s usually harmless.

Most children know the difference between pretending to be a superhero and jumping off the roof thinking they can fly.

But adults often forget.

For instance, we may stop pretending to be superheroes, but a lot of us seem convinced that we can pretend to be investors. That’s dangerous.

1. Pretend investors think that financial pornography is real, so the ticker tape scrolling across the television screen all day represents actionable information.

Real investors know it might be entertaining, like going to the circus, but they would never make a decision because of it.

2. Pretend investors think it makes sense to change investments based on what they hear in the news:

Real investors know that they make changes to their investments based on what happens in their own lives. If their goals change or there is a fundamental change in their financial situation, then they consider an alteration. But they would never make a change based on someone yelling “buy” or “sell” on television.

3. Pretend investors think they need to monitor their investments all the time. The little supercomputer they carry around in their pockets makes it so easy.

Real investors know that it takes a long time for a tree to grow, and it will not help to dig it up to see if the roots are still there. The same rule applies to investments. And because watching things get big slowly is not very exciting, real investors tend not to talk about that tree all that much.

4. Pretend investors talk about their investments — a lot. They say things like, “I’m long this or short that.” They use jargon that often does not make sense, though it sounds kind of impressive if you don’t listen too closely. Sometimes they cheer for things like increased consumer spending, higher unemployment, or in some cases, war.

Real investors understand the difference between the global economy and their personal economy and choose to focus on the latter.

5. Pretend investors will worry endlessly about the news in some far-off part of the world.

Real investors focus on the things they can control, like saving a bit more next year, keeping their investment costs low, not paying fees unless it’s necessary and managing their behaviour by not buying high and selling again when prices are low.

6. Pretend investors complain endlessly about volatility in the market and external actions that have a short-term impact on the big bets they have made on individual stocks.

Real investors have enjoyed the benefits of a market that is up more than 180 per cent in the last 20 years.

So, ask yourself this: Isn’t it finally time to stop pretending now?
