"One day, as we were winding down on set, my costar Rashida Jones turned to me and said, “Wow. You seem really grouchy.” I looked at Rashida, whom I adore, and started thinking about all the other great projects I’d worked on over the years and how every time one of them came to an end, I felt the same sense of frustration. I had never understood why I felt that way, and sometimes I didn’t even notice that my attitude had shifted. But in that moment it dawned on me: In each of those scenarios, I was angry and anxious because I was scared about what I was leaving behind. Instead of facing changes, I always wanted to skip over them."
