I think everything is depend upon your choice and desire where you want to go, because these sector if exist then it should have been some meaning otherwise why it may exist, even law demand sector also doing their work and people working there, question is only that where you are in that.

My vote is for Social Media Marketing.

Now people are addicted of social media platforms, your effective social media strategy can provide you huge unexpected returns. 

In my opinion coding is something which has a higher chance of getting you hired. But it is very monotonous. Rather Social Media marketing will help you use your creativity, thinking out of the box and life will come in different colors everyday. At the end of the day, it's what you are best at and what interests you the most. 

network administration is the good one.

Digital On Line Marketing, is Future.

If you see Contents of Digital marketing courses offered by Top Universities of Europe, they do cover in depth Social Media Marketing. Combine together they are deadly weapon tool for any organisation. 

I would recommend you to go for Digital Marketing. This is an emerging field and once you are master in this field you will earn a huge some of money.
