Feedback
What you don’t measure, you can’t improve.
I was once an avid Toastmaster, and my favorite part was the evaluation, which presented instant, honest feedback right after your speech or table-topic. It wasn’t about criticism, it was about growth. In under half hour of walking off the stage, you knew exactly what worked, what did not, and what to try next time. That rhythm of performing, reflecting, and refining built confidence and instilled improvement faster than anything else.
I miss that in the workplace. Imagine getting timely, constructive feedback after a presentation, meeting, or deliverable. Without that loop of reflection and measurement, improvement stays accidental instead of intentional.
