This whole first paragraph is all one sentence. Maybe you should give that first paragraph a few sentences:
People attend university for
various reasons, like seeking new experiences, preparing for a career, increasing knowledge, meeting new people, specializing in a field, changing the city that they were born in, making their parents proud,
to be out of the parents' eyes and many, many other reasons.
That (above) was alright before I changed it, but I am just showing you how to make it better.
This essay is great, great English. It is better English than some people who grew up speaking English. However, I disagree with this part below:
I think in these days everybody can attend a university. You can take a loan or you can attend different programs and foundations, or your grades will speak for you and you can win a grant or a bursary.
You are only thinking of people in some parts of the world; this statement is not true of people in many places. Also, it is not relevant to the focus of the essay. The essay is about WHY people attend, and it is not about whether or not people are able to attend.
