And again, not self-help, but I love recommending Shop Class as Soulcraft, by Matthew B Crawford, for reconsidering your relationship with work and finding joy in your career. The full book is worth reading, but this essay link gets the gist of it.

I wish there was a culture where good essays would actually sell for $20. Something with a "perceived value per word" review score maybe.

Personally I also really like a lot of the talks from Tony Robbins when it comes to emotional intelligence and personal psychology. I listen to them on youtube while I'm cleaning fairly often. He can be a bit over the top and rambly for some people though and I do disagree with some things. But it's a good starting point on what to think about.

I've heard this book recommended a few times but your comment made me pull the trigger and buy it.
While most self help books try to motivate you, this one explains with clarity why a large amount of people are stuck in life despite being smart and hard working individuals.
