Books are often treated like injections that we think will have an effect on us forever.
The moment we finish a book, we get the feeling that, as we have put the knowledge in, it will stay in us permanently, instantly making us smarter and wiser, and that it will be available to be used at any time.
It’s a great feeling. It’s a nice ego boost and it lasts for as long as you tell yourself that it’s true.
However, much like the majority of stuff you learned back in school, most of what you read in books will be forgotten also.
The worst part is that the knowledge nuggets that stay with you will only deceive you into thinking that you don’t need to ever read the book again — especially when there are so many more books out there tempting you the read them.
But what’s better?
A broad range of knowledge gathered from as many different sources as possible?
Or the deepest understanding possible of a particular subject gathered from fewer sources?
Like most things in life, it’s a balance.
However, in order to get that balance right, it does require understanding the sources you draw your knowledge from at a deeper level than you get from a single immersion.
Don’t think it’s worth it?
Try re-reading a book that you finished one year ago and see how many of the lessons can be applied in completely new ways for you based on the different set of problems you are facing in this moment.
