Obtaining a growth mindset takes time especially if you are used to having a fixed mindset. I consider myself to have a blend of both a fixed and growth mindset. Sometimes I find myself struggling with how I would like to accomplish certain things and then other times I don't even hesitate I just do and have to deal with the outcome later.
With a fixed mindset I feel you are afraid of the unknown being stuck in a place that you are familiar with, afraid to do something different and wanting different result but scared to get out there and see what is is about. With a growth mindset you never stop growing, not afraid of failure because you know that if you keep working at it you will eventually get better and that's where the power of yet plays a major role. The power of yet will allow not only you as the teacher but your students as well to be able to know that just because they don't know yet they still have the opportunity to learn. Looking over the graphic of the fixed and growth mind set I've come to the conclusion that a person with a fixed mindset will not move forward because they don't have the right push and take criticism to a whole new level leaving them trapped and stuck while the person with the growth mindset does something and fail but try again.
