You are splitting hairs once again. Let's see, if you do something that ultimately results in (or contributes to) you going out of business, it's a failure (PST falls into this category). An absolute failure, since it causes the worst possible effect from a business standpoint. That is, exactly the opposite of what you intended with that action.
Now, if you make an investment and that investment doesn't return the expected profit, it is a failure (it has failed), but it doesn't necessarily mean that it has hurt your business. All this, assuming that the predictions you make for the investments aren't unrealistic. If that's not the case, you'll be out of business soon, anyway.
Well, I enjoy lying on my bed, but I know nobody's going to pay me for that. Which means that, alas, I'll have to make a living somehow. If I enjoy my job, even better. But Meier's goal was basically to make a living. As you said, everything else was just a bonus.
Fair enough. But that's not much of a valid argument as backing your original statement goes, as all you are saying is that nobody really does anything to be "critically acclaimed".
