I'm really interested to see what people have to say on this topic, but I think its broadness prevents most people from responding, since we don't really know what you're looking for.

There seem to be quite a number of distinct topics that would each deserve their own post. Off the top of my head: budgeting/finances, decorating, cooking, organizing, cleaning, clothing, entertaining, mixology, etc

Could you ask some specific questions that people could respond to?

My random tip: White vinegar (the cheap kind you buy in a big plastic jug) is great for getting rid of smells. My favorite usage is for clothing and towels. Especially if you live in a humid area, towels often develop a bit of a musty smell when wet, even when they've just been washed. If you toss some white vinegar in the laundry machine while washing, it will get rid of the smell. I throw in some vinegar in each of my loads (the vinegary smell is gone once dry. Other useful usage is cleaning microwaves, refrigerators, etc.
