Analysis

In uncertain times, the real threat isn’t change itself but relying on outdated thinking. Survival and success demand new perspectives, not old habits.

Action Items

  • Reevaluate your assumptions – List three “truths” you’ve relied on recently and question whether they still hold in today’s context.
  • Seek fresh input – Have a weekly conversation with someone outside your usual circle to gain new perspectives on a current challenge.
  • Test and adapt – Run a small experiment that challenges your current approach, measure the results, and adjust based on what you learn.
