I don't know if this applies to everyone, but I'm bothered and feel unease if there's still an unfinished job at my hand.
I'd like to get things done, and I'd like to do it quickly.
This trait is tricky.
On one side sometimes it is "the quicker the better".
But on the other side, being quick sometimes makes me oversee small things.
There are also some task which requires deep thinking and actually need some time to process.
I like to listed things to be done.
And to be able to tick it once it's complete creates a good mood for me.
