From the Harvard Business Review:
We all tell ourselves stories about work, and these stories shape the way we think, lead, and make decisions. For instance, if the story that runs through your head all day is “Everything’s a battle in this office,” you’re more likely to expect hostility and be primed to attack. Negative stories like this one generally don’t help you, so consider shifting to a new narrative. Start by identifying a challenge you’re facing, and then ask: “What is the basic story I’m telling myself about this issue?” Consider how the story is affecting you and your team. Is it constraining or liberating? If the latter, think about what you’d like to change and how your story needs to shift. What reimagined (and true) version of the story would be more useful for pursuing your goals or doing things differently? Rewriting a story is often a matter of choosing to see a situation from a different, more-positive, perspective.
