Books, books, and more books! Although I also listen to audiobooks, I really enjoy reading books. I love to hold them, highlight and write notes in them, bookmark with doggy-ears, and I even love the smell of them! These are just five [no particular order] of my favorite books that have inspired and made a significant impact on my worldview. [Click on each of the books to preview it on Amazon.]
Reading autobiographies/biographies humanizes people, especially those in positions of power. I found that by reading about their biographies, I was able to get a better glimpse of their humanity, their character, and who they are as a person. No matter what I thought about their politics or decisions they made while in power, I gained a better understanding and respect for who they were/are and why they made their decisions.
I find the books below to be very valuable and I highly recommend applying all of them in both your personal and professional lives.
