Those who are too lucky

I decided to help kids from family at risks families at risk on their studies for my service learning course [1]. Notorious for keeping a stern face and an abnormal sense of dark humor, most people find it difficult to believe that I am willing to spend time with children. Believe or not, I found it rare as well. While everyone everybody [2] thinks that I am doing them the kids [3] a favor, what they do not understand is how much I learned from these kids. I have the a personality that makes me seem unapproachable. The fact is, I am indeed unsocial most of the time.

However, the children melt my heart with genuine smiles, trust and optimism. They are nothing like you and me. Most of them suffered genuine hardship in childhood,  both physically and psychologically. They might have experienced been [4] starved, abused, neglected, bullied or even raped. In their cases, poverty is no longer the worst.

Mass media nowadays has created an allusion illusion which makes most of us feel poor and unfortunate for not owning a private jet, a Hermes bag or a Porch Porsche car. Yet, how many of us would stop self-pitting pitying? When will we realize how fortunate we are that we can receive an education, live in a fine environment and bathe in love from our family? How many of us would stop whining about not having an iPhone 6 and think about those who do not even have the money to buy a slice of bread? We belong to those who are too lucky, too wealthy and too greedy.

[1] Perhaps this is a recognized phrase, but I have never heard it and therefore do not understand what you mean.

[2] Please consider this sentence:

"While everyone thinks that I am doing the kids a favor, I am the fortunate one."

Above, the use of 'everyone' is fine.

Now consider your sentence:

"While everyone thinks that I am doing the kids a favor, what they do not understand is how much I learned from these kids."

Above, there is a slight problem.  You have the pronoun 'they', which is of a plural form, refering back to 'everyone', which is of a singular form.  That is why I have changed 'everyone' to 'everybody'.

Now, this is a very subtle correction.  Most native speakers wouldn't know that matching 'them' with 'everyone' is wrong.  (Truthfully, I didn't know this until, ironically, a Chinese friend corrected my own grammar.) To use an Australian expression, I feel like a wally pointing it out.  Yet who knows, perhaps you're interested.

[3] The pronoun 'them' refers back to 'everyone' or 'everybody'.  It does not go back two sentences to 'the children'.

[4] You could use either of these sentences:

"They might have been starved, abused, neglected, bullied or even raped."

"They might have experienced starvation, abuse, neglect, bullying or even rape."

This is a well-written essay.  If we were not on Italki, I might not know that it was not written by a native English speaker.
