If you like travelling then how come you are still Introvert...Well, if you travel more and explore the wide range and the vibrant world may be it can help you shed some of your's introverted ways. Just wait for the pandemic to stop.

Coming to the profession, yes you can opt for UPSC CSE. If you could manage a rank under 200 then surely you can get IFS, Indian Foreign Service and then you can travel to various countries as an Ambassador.

All the best!!
