The problem with blogs and books is that wisdom is customized and rarely universalized.
In an attempt to scale we try to universalize things but in reality certain people need certain wisdom in certain situations.
Blogs and books aren’t able to listen or feel.
When we know people we know the defaults that they revert to, we know how they respond to fear, we know when they are fragile, we know when they need to be challenged, we know when they need to be told everything is going to be okay, and on and on and on.
I won’t stop reading books and blogs and I won’t stop writing blogs, but this is a significant limitation.
