We all want to believe that what we do matters. But we don’t. We think we do because we imagine our contribution is big. But obviously it won’t be. For example, suppose you’re raising money for cancer research.

Top 10 Reviews of Product, Games, Software, etc.

You know the current success rate is 3 percent, and 90 percent of people who try to raise money fail. So if you try to raise money for cancer research, you almost certainly won’t succeed. It could happen, but it’s pretty much impossible.

Now imagine you tried to raise money to cure cancer. That’s almost a 100 percent success rate. So if you were raising money for cancer research, you might try to raise money instead of curing cancer. But if you were raising money for curing cancer, you might try to raise money instead of raising money for cancer research.

So either way, it’s a wash. Your contribution either doesn’t help at all or doesn’t help as much as you think it does. Similarly, when you write book reviews on Amazon, what difference does it make if you help or don’t help? It can’t possibly matter.

But here’s the thing: it is a surprising number of people for whom it really matters. A very small percentage of people, in fact, help a lot. And if your reviews help those people, then you made a big difference in their lives. But most reviews are worthless. So even if it helps one person, it’s no better than not writing the review. And helping one person is worse than not helping.

But here’s a twist. Let’s say you write 100 reviews. And let’s say 10 of those help people. But let’s say that of those 10, 5 are people who would never have read your book anyway. It doesn’t matter if they read it or not, because they would have read it anyway.
