The Subtle Art of Not Giving a F#$% by Mark Manson was recommended to me last year by the counsellor I was speaking with for help with some mental health issues.
The core message of the book is: "We only have so many f#$%s to give in this life, why waste them on stuff that's not important." The author explains how we're not as important as we think we are sometimes, and relates that to getting one's priorities in order and ultimately, learning how to relax and not stress out as much.
Around the time I bought the book, I was doing a lot of worrying, especially about trivial stuff like the weather and Para Transpo being a little late/early. "Subtle Art" helped a lot with managing that, and the crassness was a welcome bonus.
Highly recommended for anyone dealing with similar issues.
Cheers!
