Choices

Greetings

I didn't think much about my future career when I was in the last year of school. I just knew that I liked writing stories and I wanted to have enough money that I didn't have to worry. Now, I accept that my priorities were overly simplistic, and I was a fool. But it could have been worse.

At that time I took a entrance test for an important public university here. My two career choices were economics and literature studies. If I had obtained a good score, it would have been possible for me to study economics there. If I had obtained a slightly lower score, I could have studied literacy. With a bad score, I wouldn't be admitted - as was the case.

In the end I decided on economics. I confess that i chose this because it give me a high probability of living a life without financial worries, at least compared to literature. You need be talented to get published, but more importantly, even though you reach that objective it's really naïve to think that in a country like this -where people don't buy books, and don't even read books - writing is a good choice.

I've marked the spelling and grammar mistakes in yellow. Where I've rephrased something so it sounds more natural, I've marked it in blue.

I changed "literacy" to "literature". "Literacy" is the ability to read and write. "Literature" means fine written works such as novels, essays and poetry.

Subjects such as "economics" and "literature" aren't normally capitalised.

You don't need to capitalise "it".

Good luck with your career in economics, if that's what you're going to continue with.
