In today’s fast-paced and highly competitive corporate environment, it’s never been more important for your leaders to push pause and reflect on what happened last year in order to best plan for the year ahead. Reflective thinking can help leaders prepare for the future & thrive in the following five ways:

1. Gives True Perspective — What were their successes? What did they learn? It’s important to reflect on experiences because human beings have the tendency to take things for granted.

2. Gives Emotional Integrity — Reflective thinking enables leaders to distance themselves from the intense emotions of particularly good or bad experiences and stop carrying around emotional baggage.

3. Gives Confidence in Decision-Making — Every leader must make snap judgments from time to time—and later wonder if he or she did the right thing. Reflective thinking can help to diffuse that doubt.

4. Helps Keep the Big Picture in Mind — Reflective thinking puts ideas and experiences into a more accurate context. It encourages leaders to ponder what had been done and observed.

5. Takes a Good Experience and Makes It a Great Experience — It’s not necessarily experience that is valuable; it’s the insight leaders gain because of the experience. Reflective thinking turns experience into insight. An experience becomes valuable when it informs or equips leaders to meet new experiences.
