Saying Hard Things the Right Way
Although this TED Talk primarily focuses on speaking up in the workplace, the speaker offers a model that can also be applied to personal relationships. Instead of remaining silent about a tough topic, she suggests following the "Moral Compass"—a principle she learned from her mother.
If you want to skip her introduction and applications to the work environment, start at the 5-minute & 45-second mark to hear more about this principle.
Following the Moral Compass involves turning to a symbolic North, South, East, and West:
N = North Star (following your better values)
S = Support
E = Empathy
W = Wonder (curiosity)
