Beyond the laugh, though, I find that a very strange rewording suggestion. Usually the advice (and I've found this good) is to make the to-do more specific and concrete. An open-ended project-sized item like "organize my finances" is a foolproof candidate for procrastination. "Do my taxes" is better, but might still be too big depending on the complexity.
A real to-do for either would be something like "Collect tax forms and order by date (note: there may be one under the couch?)" -- it's reasonably scoped and has a very clear "I'm done" criterion.
(EDIT: Looking at the article, it seems that "breaking it down" is indeed the suggestion. The specific wording chosen is still strange; it seems the author means something close to "gather documents" by "organize my finances".)
