Aaron wonderfully summarizes Carol Dweck's study in which she gives kids to solve challenging puzzles. The kids who failed to solve the puzzles change their state from struggle and self-doubt:

“I never did have a good rememory”

to disappointment and frustration:

"This isn't fun anymore"

to accepting defeat and resignation:

"I give up"

and finally ignorance:

They started talking about other things, trying to take their mind off the onslaught of tricky puzzles. “There is a talent show this weekend, and I am going to be Shirley Temple,” one girl said.

As I kept reading, I could really see myself in same stages when I faced difficult challenges from my past experiences.

But the response of successful kids were completely opposite - they showed determination and persistence:

"The harder it gets the harder I need to try"

I believe that's the difference between those who stand out and achieve their goals and those who don't. It's the "growth mindset" that leads. I always revisit to this essay when I feel that I am having the "fixed mindset".

And I always remind myself that :

It took a seventh-grader to explain it to her: “I think intelligence is something you have to work for...it isn't just given to you... Most kids, if they're not sure of an answer, will not raise their hand...But what I usually do is raise my hand, because if I'm wrong, then my mistake will be corrected. Or I will raise my hand and say..."I don't get this. Can you help me?" Just by doing that I'm increasing my intelligence.”

So believe that you can get better and focus on growth.
