Dear Aspirant,

As much as I can understand your query, doing a PhD it something which needs to come fully from you as you are supposed to do it by your own. People only do PhDs when they are interested to research or study something in great detail & have an outcome that is rare. For the same reason, I'll suggest you to get in touch with PhD students (active/passed) from PhD community on networking sites like LinkedIn. Mere interaction with students who have undergone or are undergoing the same will open many doors for you & make your doubts clear. Kindly interact with them & research on topics that interest you.

Thanks.
