Interviewers ask this type of question to see if you have drive, ambition, initiative, and aspirations of becoming better than you currently are. If you can't answer this, then you are essentially showing the interviewer that you may not have any growth potential. Nearly every field has certifications, so throw a few of those into the mix.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
