Touches on the big topics of 20 something ‘success’ (e.g. career, family, friends, money, etc.) and surrounding stereotypes of those in their 2nd decade on earth.
I’d say my key takeaway from this book is the need, value and potential consequences for putting off planning for the future in terms of career, family, wealth, friends, etc.
I would read up in these areas separately for anything of substance on how to think about what success would look like for you in these areas and I’d be reading and recommending think & grow rich, 7 habits of highly effective people, and many others before this book for anyone looking to get some structure post high school and university.
