2. Change or Die by Alan Deutschman (1965)
In general, you should read every single book written in the 1960s. Most writers were tripping on acid so it just makes reading more fun that way.
3.The Way of the Superior Man by David Deida
Boys shouldn't legally be allowed to turn 18 without having read this book. No woman should even consider marrying a man who hasn't read it. And no man is a real man who doesn't know and apply what is within its pages.
4. Pitch Anything by Oren Klaff
Best book on sales and persuasion ever written, period. If you could read just one book on selling, it should be this one. Actually you should just read one book on this topic. And it should be this one. There's literally no need to know anything else. It's amazing to me that almost no one has read this.
It's applicable for every human being on earth no matter what your profession. If you're living, you're selling. And you have to sell well to live well.
5. Markings by Dag Hammarskjold
"What should we name him, hunny?"
"Oh, I don't know. How about Dag?"
"I love it!"
Markings is the Christian equivalent to the great stoic Marcus Aurelius' famous book Meditations (also worth reading)—a collection of short reflections and advice about life in general. This is my favorite one:
Is life really so wretched? Isn't it rather your hands which are too small and your vision which is muddied? YOU are the one who must grow up.
