"I inherited a district that was underperforming, a lot. It was overwhelming. I suffered from task paralysis and had trouble getting started. Long ago, a mentor suggested in situations I always tackle the biggest aspect of an overwhelming project first, since that was what I felt most daunted by. It was good general advice, and I listened to it. However, in this instance, I should have taken a different approach. I lost focus on the priorities of the project, where instead of focussing on the locations one by one, I should have looked more closely at the broader view of the problem at hand, which was the messaging of what the company's priorities were. As a result, I didn't manage my time right and should have approached the project differently. I missed that target, but never made the mistake again."
