Hi Rahul,

Success is a subjective term and could mean different things for different people. For some it's money any for others it's just fame and for that rare breed of people, it just means doing what you love without a care about what others would think. You can achieve success in any field provided you are dedicated and focused to the work provided to you.

For a more objective answer, learning a foreign language helps your career a lot as there is increasing demand for translators etc.

As far as MBA goes, while it is true that MBAs from a well-renowed college makes it easier to get a job, you can override that by doing extremely well on the course.

Hope I was helpful and good luck!
