Philosophy Corner: "DESIRE". What is there to philosophize about this "sense of longing for a person or object or hoping for an outcome"?

I read an contemplative piece today on the (longing for a) cigarette.
In short the author stated that: we (the smoking people) long for one, then we light one, and after a few puffs the craving is satisfied, after which we soon long for another one and another one, and another.
Apparently philosophers have written lots of words on desire in the past centuries.
It got me thinking on how this thing works; the longing for, the getting it, and the satisfaction.
What are your ideas, your thoughts, on Desire?
