Why???

It is half past midnight!! Bleary eyed, I am sitting and staring at the monitors in my office cubicle!! Working, voluntarily and not complaining about it. Working on weekends as though it is a working day!!
I don't have to impress my boss or prove to my colleagues that I am good. (I have one of the best teams in the world to work with (No pun intended!!)).
This is not something that happened to me on a blue moon, it happens almost every day.
Why??
I have no idea..
This is the answer that I am trying to search through this.

My girlfriend ditched me coz i cud not give her enough time, my friends complain all the time that I am too preoccupied, I see my MOM once in 2 months, though she stays just 200 miles away. Why??

I have always done it out of my own interest, and everytime invariably I have been utilized by people. I know it and still can't change myself!!

Hopefully someday I will change and spend more time on myself!!
