Not to be a contrarian, because I agree for a lot of the industry, but there are some genuine gems out there. Few examples:
Extreme Ownership really helped me be a better leader and take more accountability for my own actions
Atomic Habits really helped me think about goal setting and what the underlying driver was
Coaching Habit improved my 1:1s drastically (I basically stopped talking or advice giving and just listened -- profound, I know, but the book helped smack me in the face with it)
Many more examples, but there is definitely a ton of self-help hack slop out there as well.
Totally agree. So many people talk when they should listen.
I'd agree with that. A lot of rubbish is out there, but there are some helpful things. Even the Law of Attraction can be helpful if viewed through the lens of positive thinking (i.e. you can handle bad situations better if you are in a good frame of mind which will make your life better.)
