The Defining Decade: Why Your Twenties Matter - And How to Make the Most of Them Now

2.5 stars. some good tidbits here and there, but very obvious that the target audience are upper/upper-middle class, straight, neurotypical, white people that want a nuclear family. her research was done between 2011-12 which is already out of touch with the current state of the world, post-pandemic, gen-z, etc. and is highly apparent when reading the anecdotes.

Read in one seat. It's well-written and backed up with some scientific research. It's not dry, most of the content are examples of people who spend their twenties as they wish and face the consequences in their thirties or later. Sometimes it's pretty sad.

Main messages are "learn to front-load your pain" and "every minute counts, at any age".

I'm glad it's not an eye-opener for me. I wish I could recommend it to some people I know but they won't read it.
