I am planning to apply to NTU and have just started with essays.

1. If you were to choose the single most important thing that matters to you, what would it be and why?
  (Share the experiences, lessons and insights that shaped your choice). (300 word limit)

I am not sure how to approach this?Any guidance is greatly appreciated.

Thanks
P.Prakash
