Minimalism and de-cluttering are rising trends, attested by the popularity of Marie Kondo's New York Times' bestselling The Life-Changing Magic of Tidying Up.
The target audience would be anyone in their twenties to forties--students, young professionals, and young families who struggle with debt and budgeting while owning too much stuff, as well as baby boomers looking to change their lifestyles. Millennials especially are beginning to eschew the consumerist and commodified culture they grew up in, valuing essential, minimalist living instead.
The book offers a holistic angle of the topic, combining minimalist life philosophies with practical tips and action points to remove non-essential physical and mental clutter.
