Why such a title? Let's take a look together.
What was the impact of the advice you followed? Why all this literature, Youtube channels and blogs are telling you what's the most important thing to find in life to be happy and fulfilled?

Why do you feel so insecure and stuck in your own thinking? Why do you no longer know what you really like and want? This book will help you get rid of what's stopping you from finding what you're looking for, and free your brain, at least a little.
It's a short book and a quick and easy 10-step program that can be completed in about 2 weeks. You'll also learn to question everything to make sure you're not replacing a silly belief with nonsense.

This is the multitool that everyone who wants to change their life and every job seeker needs.

In case you'd rather choose another book, let me offer a recommendation that I hope will help you to be more vigilant and clear-headed in choosing a method of reorientation, and it also works whatever the subject:

Question reasoning or references based on beliefs, advice, sayings, norms and stereotypes, quotations, scientific studies and historical accounts altered to argue a point of view, convincing sophisms, and especially at the level of your reorientation, those "theories" or "methods" of career choice biased by their author's way of thinking that don't really leave you the freedom to think.
