Could you check out this paragraph?

While I think about what career to study, I'm afraid of making a bad decision. Some people make this decision based on what they have seen, friends or family that already have a job. I wonder if it is a enough reason, believing that you are going to find a job if you study the same thing that a lot of people studied too. I know, I only have to study what makes me happy, but, it is not easy when you don't know every profession in the world, so you could make the right decision. Or maybe you can make this decision taking into count what you are better at, maybe you are really good at math, that's your talent, so you should study some career related with that.
This is not an easy decision, how can I choose? How would you advise to someone that has not decided what to study?

Adrian's done a good job of correcting your discussion.

My comments are about choosing a career.

Many people do not know exactly what they want to study or do as a career.

But everyone has an innate talent or a strong interest in something.

Pursue what you love (or what you like very much)

Here's my story:

I found chemistry easy in school

I became a research chemist

After a few years I used my knowledge of toxic chemicals to become an occupational health and safety consultant.

One of my consulting duties included training managers and workers in many companies (30,000+)

I enjoyed training people

I retired and became an italki teacher (training again)

Here's the point I'm trying to make:

1  Study or start in the field you like.

2  Later you will see many directions that you could work towards

3  Finally you'll find what you enjoy the most.

buena suerte
