I think I need some research assistance.

As some of you may know, I write a monthly column for homeowners. Generally I recommend products for projects around the home or teach people how to do projects themselves within my columns.

For next month's column, I want to convince homeowners that maintaining and improving their castle will lead to a more satisfying and contented lifestyle not only in their home-life but professionally as well.

I think I can present my opinions in a well-reasoned manner but I'd like to also reference studies that may have been done on the topic.

I've had this column idea for several months but have been unsuccessful in locating proper resources in many attempts. Any ideas?
