Well, finished the book and loved it. At first I was afraid it might go in a spendy direction (which is fine I could just adapt for what I'd like it to be), but then I read the chapter Hygge on the Cheap and found this:
"Hygge might be bad for market capitalism, but it may prove to be good for your personal happiness. Hygge is appreciating the simple pleasures in life and can be achieved with very little money."
Also, bike riding is a part of it. There is a section of a chapter entitled "Bikes and Happiness." Very MMM indeed.
So, while I've always loved getting cozy (particularly in the winter), I'm glad I found this book.
