The Six Pillars Of Self-Esteem. Even if you think you already have high self-esteem, there's no such thing as too much self-esteem. Someone here on HN first made me aware of it. It's such a great framework for self improvement. I've read it 3 or 4 times and did all of the exercises the first 2 times.
I’m way more honest about my values and whether my actions align with those values. When there’s an inconsistency between my actions and values I either realize that the value is not actually a priority and I have the peace of mind to let it go, or I’m motivated to change my actions to align with my values.
It's slightly distracting but it's definitely a don't throw the baby out with the bathwater situation for me. I can see how it'd be easy to take in the book's ideas and get seduced into libertarianism, but I can personally testify that it's possible to read the book without subscribing to libertarianism.
