Awareness of the hedonic treadmill meshes quite well with my 'frugal' Yorkshire tendencies.

A favourite on HN seems to be coffee, and spending ever more on 'good' coffee. I mainly just drink instant coffee, filter coffee for the weekend. I still get my 'good' coffee and I appreciate it. Same goes for wine and chocolate.

It's also led me away from expensive experiences to unique/different experiences.

It's also helpful for informing new purchases. Do I need the latest car with all the bells and whistles or can I just stay a generation behind and be excited with a new car with electric windows or whatever.
