The book is an ode to do more and to take agency of your life; a Nietzsche rightfully reintroduced. While my takeaways differ from Nate's, it showed me a side of Nietzsche that I had not considered before, in a form not bereft of hyperbole, most fitting to Nietzsche himself.
In short - have a go at the book, make sure it takes you two years to read because you are reading it only when out by yourself in a loud pub, and who knows, you just might want to join Nate's invitation in the end.
