To study or not to study

It's that time of year again. The call for postgraduate study scholarship nominations is out.

The last 90 minutes have been spent searching for suitable engineering & engineering management postgraduate programs in the UK. While I found a few that would have been attractive to me 5 years ago, I wonder if I still have the tenacity and the attention to detail to do something purely technical for 3 full years. Not to mention that it has to be 'aligned to the Company's Technology Agenda', in which my current work does not feature prominently at all.

I'm not sure whether it is something I really still want to do, or just a feeling that it's something I should've done before that features so prominently on my 'to do' list, like ganti puasa. Or it's something that I need to do because it's expected of me and I just can't bear the idea of people going "You should have" for the rest of my life.

Why can't I just be satisfied with staying at home to breed like a rabbit?
