Is there something I should be doing with my tiny amount of money?

No, it says “is there something I should be doing,” in other words, “Is there a sweater I can buy with this amount of money.” Not “what sweater should I buy,” but “what sweater(s) is/are available?”

By the way, what are you referring to with the phrase “personal finance?” Because the way I use the phrase, I don’t take myself to be asking about personal finance. (Topics near and about the area, but not about personal finance per se. Just asking a question about where money can be spent is not the same as asking a question about personal finance in general.) So I need to get clear on what you mean by the phrase.
