Suppose to

Who determine what we are 'Suppose To' do?
Is it God, ourselves, others, feelings, urgency, promises, or???
Well, I guess all of us hv used many other factors to determine 'Suppose To'.
Some factors are just subset of another... and they overlaps.

Well... that's not the point actually.
The point is, I am Suppose To be doing my assignment...
And apparently, I'm not. Cos I simply can't get myself started.
:( This is depressing.
I've wasted the whole morning.
