hey guys I have an idea for a common app essay which is basically about how an experience made me reevaluate being a pessimist and made me an optimist and this has affected how I approach challenges
Any feed back would be appreciates 
is it a specific experience? or just a couple of experiences over time? i think this generally is a good idea, just make sure it reflects your story and your growth as a person/student
This is the best application essay idea that I have ever encountered on College Confidential. And I am serious.
In short, you understand.
