Should not there be "anything" instead of "nothing" in this sentence? [closed]

Solution 1:

I think it's correct as it is.

In the quoted passage it says you are "losing yourself to everything but the goal of capturing and documenting this language". In other words, you're focused on this one thing. You're focused so much that "You'd rather do nothing else".

If you said "You'd rather do anything else", you're saying that you want to do anything but the task of capturing and documenting this language.
