Why am I still trying ?

It is nearly 2am here and I am still coding. There are still a number of things to do and all of them are needed to bring out the idea.

So why am I still holding on ?

Well, there 2 reasons here.

1) Sunken Cost fallacy.

2) For the sense of accomplishment at the end of the journey.

What about you ? Why are you still doing ? Especially for those in the same timezone as me :D, why are you still up at this hour ?
