'elastic material's ability to absorb the energy'; Spring = Me?

What attribute of your personality are you most proud of, and how has it impacted your life so far? This could be your creativity, effective leadership, sense of humor, integrity, or anything else you'd like to tell us about(200-250)

In physics I learned about an elastic material's ability to absorb the energy that is being forced on it in order to return to its equilibrium state after the compressing or stretching force has been uplifted. Resilience is the ability for one to return to his/her normal routine after being pressured by an outside force. I believe I have been blessed with this trait were coping with an adversity may seem hard at first, but in the end the persisting force will be upheaved letting the string to originate back to its initial form.

The proverbial phrase "when life gives you a lemon, make lemonade" evades my mind when faced with difficulty. Although the words of wisdom translate very easily, the true definition of this phrase holds more depth than it lets on. For instance, it can be considered as a way of turning something sour to sweet, or turning bad incidents to beneficial ones, but to me this adage turns into a lifeline one which bases a standard of using all the available supply or situation to turn the tables around and set my own rules down and turn yesterday's bitter incident into tomorrow's sweet refreshment.

Resilience does not only mean coming back to my original state, it signifies my rising from the ashes into becoming a better and stronger person that can handle whatever else might get thrown at me.

While the physics information enhances your essay, I think it would be better if you included more personal information and less scientific information. Tell the admissions officer something that happened to you that shows your ability to recover after adversity. Have you been discriminated against before? Did you fight back? Has something bad happened in your life that you've recovered from? Something like this would be great. There are a few grammatical issues:

"with this trait were (should be where) coping with an adversity may seem hard at first"
"letting the string to originate " Do you mean "return to"?
"evades my mind when faced with difficulty" I think you meant "comes to my mind". Evade means it avoids your mind.
