I just put my kids to work but am running low on those. On the other hand, less messy with less people.
Seriously teach your teenagers how to clean, change tire, cook, do laundry, etc. Sad how many college kids are clueless.
My Mom used to pay me to clean stuff - wash the kitchen floor, clean the bathrooms, vacuum, dust, etc. I learned how clean a house (properly) and also had some extra pocket money.
