How so?

For example, how are these wrong or irritating?

"Ask a person to draw the screen from memory and only the most important things will be remembered"

"Users always come with feedback in the form of solutions, not problems. Try to understand root issues."

"Try it and look at the data for decisions. Don't be attached to your decision"

Is it irritating because you find these obvious? I could see that. But the same way I know I should exercise more, eat better and sleep more, while still not doing it, it's always good to hear/read good advice again and again.
