I read this in "Word by Word" by Kory Samper:
You toil onward with steady plodding, losing yourself to everything but the goal of capturing and documenting this language. Up is down, bad is good and the smallest words will be your downfall. You'd rather do nothing else.
What is the last highlighted part supposed to mean? Is there any pun intended? And shouldn't there be "anything" instead of "nothing" which would imply that you are so tired of the work that you'd anything except that?
