Read The most important thing - Mark Howards.

Here are some books Buffett has recommended, I'm sure there are tons of other books, these are just the ones that have stuck with me.

Investing:
1) The Intelligent Investor - Benjamin Graham
2) Security Analysis - Benjamin Graham
3) Common Stocks and Uncommon Profits - Philip Fisher
4) The Little Book of Common Sense Investing - John Bogle
5) The Most Important Thing - Howard Marks

Economics:
1) An Inquiry into the Nature and Causes of the Wealth of Nations - Adam Smith
2) Where Are the Customers' Yachts: or A Good Hard Look at Wall Street - Fred Schwed
3) stuff by John Maynard Keynes (never heard him mention exact title)

Others:
1) Poor Charlie's Almanac - Charles Munger
2) Business Adventures - John Brooks
3) How to win friends and influence people - Dale Carnegie

Then there are some things I've never heard him explicitly recommend but I think are definitely worth reading:
1) Letter to shareholders (all of them, you can find the ones of his partnership and earlier ones online)
2) The Snowball - Alice Schroeder
3) Tap Dancing to Work - Carol Loomis
(There are tons of books on Buffett, but these two are friends of his)

Also, if you ever go to his shareholders meeting, there's a whole list of "Buffett approved books". Some that I can remember from this years meeting (other then the ones mentioned above):
1) all of them found on https://www.poorcharliesalmanack.com/
2) Dream Big - Cristiane Correa
3) a bunch more that I cant remember

Finally on his investing, he has laid out a bunch of times what he believes is best for ordinary people who aren't going to devote most of their time to investing namely, buy a low cost index fund (he recommends Vanguards, I believe it was this one https://personal.vanguard.com/us/funds/snapshot?FundId=0540&... )
I'm not quite sure why so little people (that I know) listen to him. It seems that people want to show that they can outperform the market, but rarely do.

For sure! Our "textbook" was "Influence" by Robert Cialdini. Here's a number of others:

-"Thinking Fast and Slow" by Daniel Khaneman
-"The Undoing Project" by Michael Lewis
-"Fooled by Randomness" and "The Black Swan" by Nassim Nicholas Taleb
-"Pre-suasion" by Cialdini
-"The Moral Animal" by Robert Wright
-"The Most Important Thing" by Howard Marks
-"Everybody Lies" by Seth Stevens-Davidowitz
-"How to Fail at Almost Everything and Still Win Big" by Scott Adams
-The "Freakonomics" Trilogy
