9. Beware of “time bullies”. When you are on the clock or supposed to be working, your time is for your work. Protect it. Say no more often. Don’t get suckered into tasks you don’t have time for.
The whole culture of critique around design is nuts; most people in most companies thinks design is just opinions. They think it’s a big subjective cesspool, and so if you’re living in a data-driven organization there’s this belief that all opinions are created equal–which is absolute bullshit–but everyone thinks they can say whatever they want about the design and somehow the designer is supposed to respond to that. And it makes them nuts, or at least frustrated.
