“A user’s mind is complex. You should know; you have one, (I assume). UXers work with subjective thoughts and feelings a lot; they can make or break your results. And the designer must ignore their own psychology sometimes, too, and that’s hard!
Ask yourself: What is the user’s motivation to be here in the first place? How does this make them feel? How much work does the user have to do to get what they want? What habits are created if they do this over and over? What do they expect when they click this? Are you assuming they know something that they haven’t learned yet? Is this something they want to do again? Why? How often? Are you thinking of the user’s wants and needs, or your own? How are you rewarding good behavior?”
