Asking for grammar for my too-long-and-too-confusing-to-read essay :P, thx

"Hey, do you know that girl? " One of my friend told me
"Nope. Do you know her? " I answered
"You must be kidding me. How come you don't know her. She is in the top rank of students with high score here. She is the winner of International Mathematic competition. Many lecturers know her and ask her to get involved of some project.. She will be graduated faster with absolute point, cumlaude predicate. I think you have gone to mars for some month so you dont know her." My friend keep talking and talking, I didn't know what i feel.

Well, here, there are too many gap, between them who are neglected, and them who are popular.
Me, in this term, maybe the unpopular and too ordinary girl. Sometimes I feel regret, and say to my self i think what I've done is not optimal, and actually i can be more and more popular girl with many achievements. Sometimes I blame my self and sometimes i blame others, like why did my dad ask me to take the course that actually I don't really like? or why do I always get the unapropriate lecturers who always give me bad marks even i have done my best?. Iam still keep doing that, untill i realize one thing

One day my teacher told me "Never underestimate other. Because if you do so, you are actually worse than that person." I try to always remember what she said. And I just realized that even though I am the ordinary and unpopular girl, I have ever felt that I am better than other, in some sides. So, Bingo, here I am, who have ever underestimate other.

What I want to underline here is, If Me, the unpopular and ordinary girl has ever underestimate other, how about the popular ones? How many time they will underestimate other or at least how many sides that they can think that they are better than others? And I found that, being unpopular is much better for me. At least There is only a few side which I may underestimate other.

And if there is a popular girls with so many achievements but that girl never underestimate others, She is the best because underestimating others is the biggest temptation, for them who are popular and have so many achievement around.

Whew, well, just never underestimate other, friends, no matter how unpopular or how popular you are !
