I completed my 12th from science stream but have interest in writing about social topics in Hindi. What should I do?

Hi Avinash, If you have an interest in writing in any language, I would suggest you to take mass communication or media science, where you can write on topics, which includes social topics.

If you have interested in writing, then you can probably pursue mass communication and further make your career into writing. You can become an article writer about social issues.
