And I am thinking. Aren't they the opposite things? If you try to avoid these fallacies, all or some of them, it is going to be a premature optimization. Especially early on, and especially if your team is small (like we know is best).

Of course, I am not opposed to the fact that all these 8 points are bad things.

My point is a question on how much should one worry about them when laying the foundations of their product? Aren't these fallacies (or at least some of them) unavoidable if we follow Knuth's rule? We all know lots of successful products which fail in some of these.
