What does it take.....?

Its exactly 1.45 am, and I have a zillion questions in my head right now starting with "What does it take.....??"

Would be hard to enumerate all of them, but here is one which seems to be perched on the edge of my forebrain "What does it take to go to bed knowing you should probably not go to sleep right now?". This would be a thought for every person on this planet who knows he/she is trying to grab 40 winks even though something is left unaccomplished!

Whilst my 4 odd years of engineering this question seemed to linger every 4 months in my head when I was preparing for exams and uncountable KTs. Today I have it in my head again.

P.S. This is my first BLOG ever, thought I would give it a shot :), hence the title!
