Your question is Proud Achievement and Challenge. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Talk about a realization you are proud of and what the main difficulty was.
Choose a specific professional example and explain what changed in your thinking, why reaching that realization was difficult, and how it affected your behavior or decisions. Focus on your own role, the evidence or feedback that shaped your insight, the outcome, and what you learned.
