The primary audience is university-educated urban millennials (roughly 21-35) who hate their job. 50:50 gender balance. This is the sort of book you would pick up in Urban Outfitters or Oliver Bonas. UK focus.
This is the story of my average reader:
"You started panicking in your final year at university (or an apprenticeship/further training etc) about which career to chose so you took a scatter-gun approach to applying for jobs. You accepted the first one you were offered, not really giving much thought to what the job actually entailed or if you'd be well suited to it, instead you thought about whether or not you simply were employed and then if it was a "good" job with a "good" salary.
It's now 1 to 10 years later and you're realising that you life is going down a path that you don't really want it to go. You are working really hard, only just making rent, you are outwardly successful but are deeply unfulfilled. You know you need to make a change in your life, but you don't know where to start or what else you would do career-wise."
This is where THE RADICAL SABBATICAL steps in.
There is a working subtitle of 'The Millennial Handbook to the Quarter Life Crisis'.
