Emotional Training Books…Where to buy?

I found the following books from another Reddit that teaches emotional control and good reads.

1. Emotional Intelligence by Daniel Goleman
2. Non-violent Communication by Marshall Rosenberg
3. Permission to Feel by Marc Brackett
4. Never Split the Difference Christopher Voss and Tahl Raz
5. Happiness Advantage by Shawn Achor
6. Resilient, and Harwiring Happiness both by Rick Hanson
7. Mindset by Carol Dweck
8. Feeling Good by David Burns

Now, my problem is where can I buy any of these?

I just literally started to realize myself how weak and immature I am emotionally, and I want to improve it by trying to read books.

I am not sure if Amazon sell hard copies or Kindly type. Or if anyone has old and no longer use books, I will be more than happy enough to take care of it.
