A pragmatic and nice guide for 20 something people, but not only, focussed mainly for people in the USA. Obviously a lot of tips about finance, salary, etc; are focused on that market and not really matter for other part of the world. Nevertheless, it's full of wisdom, and quite easy to read (sometimes a bit long on topic you might say "okay yes, that's common sense).
That book should have been a card game or a calendar. The medium seems odd since each page is a bite-sized reflection (close to being a prompt, to be honest) that pushes you to reflect on it. There were a LOT of things that resonated deeply with me and the way I'm doing business, so I liked it, but it might be very subjective 😄.
The first time, I read it 3-5 pages at a time and took time to think about examples I've been through. Then I read it straight from start to finish. In between, I just opened a page from time to time.
