It is always interesting when I get to revisit the book's concepts in my brain that I thought I forgot or did not grasp. It is great to go back and re-read the book for them to stick and even make notes for future references.
I read books and after finishing them, I only remember a few concepts from it. After maybe some days as I am doing something unrelated. I have thoughts or even ideas and I find myself referencing subconsciously some of the passages from the book.
The last three weeks I have been going on long walks. The first days it just the usual but with time I found myself analyzing the thoughts and ideas that came about. This has helped me with clarity in my life. I still have a lot to unpack but it's a great start.
Reading books open you up to new perspectives as you learn of how the experiences the author has gone through have shaped him/her. You become more empathetic and judge less. At least that is what has happened to me so far.
Regrets are not a bug but a feature of life. They are a natural by-product of us being curious about what could have been. And given the fact opportunity cost exists, there are always going to be regrets.
Social media mitigates this since you can see how a creator evolved through the years. You get to see how their experiences have changed them through the years.
Its difficult for people to find a role model that they can genuinely have an affinity with, because most of the people you look up to are talented or successful. By design you don't have that much in common.
