We can get so fixated on our own anxiety about asking for a raise that we forget to consider the situation from our boss' perspective.
Daniel Shapiro, founder and director of the Harvard International Negotiation Program, and author of "Negotiating the Nonnegotiable," previously told Business Insider that it can be helpful to grab a friend and role-play the negotiation, with you as your manager.
"Really emotionally take on that role," Shapiro said. "How are you feeling? Do you feel attacked? Do you feel defensive? Do you feel like this idiot did no preparation in terms of coming in and asking you for the raise?"
Once you take on the boss' thoughts and emotions, Shapiro said you can further tailor your strategy (as the employee, in real life) "so that the boss can most effectively hear what you're saying."
