Hello dear...

is a loaded question if there ever was one. Each person's definition of success varies. I might consider myself successful if I had one test that went well, no matter what the test was.
For a complete answer to this question, one requires a complete definition of success. Is success defined by academic accomplishment? Or by industrial implementation? Maybe by an integration into societal and social lingo?
Whatever the answer is, one can only determine the extent of success, if given the domain of applicable values of said success.
Thus, I am completely allowed to say that, even though I have not achieved either glory or gratitude, I am the most successful SASTRA alumnus.

Best of luck...
