It (growth mindset) is the belief that qualities can change and that we can develop our intelligence and abilities. The opposite of having a growth mindset is having a fixed mindset, which is the belief that intelligence and abilities cannot be developed. -Eduardo Briceños

I have not always had growth mindset. I was the youngest of 3 children. My parents were almost 40 when I was born. I was the miracle child, the golden child. My mother will tell you I was the easiest to raise, I was good at school, and I got along with everyone. I was told my the adults in my family how wonderful I was, how smart I was, how talented I was, and I believed them. School came easy and I achieved many awards throughout my school career (varsity letter, National Honor Society, academic awards, musical awards). Then I went to college. I found out maybe I wasn't so special and smart. I didn't get into the elite choir, I didn't get into advanced writing as a freshman, and I flunked a test. Suddenly I questioned my worth.
But somewhere along the way into adulthood I figured out that I could learn and I could grow and I could fail. That's right-I could fail and it was ok. I learned how to bounce back from failure. I learned how to reflect and adjust. Then I learned how to look at my students and try to help them learn how to grow and learn from mistakes, learn from failure. 
Now my challenge is to help my colleagues. Some of them already have growth mindset and are accepting this coaching situation as a time to grow in their professional practice. Others still are not sure. They want to be perfect the first time. They don't want to be told that they are "wrong". Luckily it's not my job to tell them they are wrong. I'm here to help them learn how to reflect and look for ways to make it better. After all, we can always get better.
