> The market rewards being right in a way that no argument ever will.

But it doesn’t. We don’t live in a meritocracy. You could have the best product in its category while selling very little, while your competitor which is a multinational corporation with an inferior product beats you on marketing and price to a level you could never match.

There’s a reason “the market can remain irrational longer than you can remain solvent” is a popular saying.

The whole article would’ve been better without that whole “Don’t Win the Argument, Profit From the Difference” section. Its inclusion muddies the point and shifts the perception of the author’s motivations. Most ideas in the world which are worth debating don’t immediately translate to money.

> In this world, there is no one you can change. Not your spouses, not your friends, not your kids, and of course not strangers on the internet.

Myself and a long time friend would be the first to tell you that we were profoundly changed by each other. We are very different people from when we met, and have each other to thank for a lot of that.
