Why HN recommends it

Sci-fi novel about Lazarus Long, who lives over 3,000 years, looking back on a long life. Fans value its self-reliant, skillful attitude, its philosophical range and a moving love story; many reread it every few years.

    …book as collecting a soul. If you fully grok a book, you grok the authors thoughts. Being able to put yourself in another persons mindset is crucial. Speaking of "groking", Stranger in a Strange Land, Time Enough for Love and The Fountain Head have probably had the most impact on my mindset. Each book is rather different, but in general the idea of all three is > You have to be in life for yourself, and only you can…

    …only in a linear fashion. Technology is a productivity multiplier. I refer you to the Robert Heinlein short-story "The Tale of the Man Who Was Too Lazy to Fail," which is provided in his magnum opus "Time Enough for Love". We should be "working hard" on finding ways to be lazy. It's through the pursuit of technologies that allow us to be as productive as we are on less effort that make the big advances in productivity,…

    …motivational because I want to be one of the people to build something like a skyscraper making me worthy of calling myself human. 2) I read inspirational books, to me The Fountainhead (Ayn Rand) and Time Enough for Love (Robert Heinlein) are always inspirational because they project characters that are considered "ideal" or at least worthy of aspiring to be. I also read a fair amount of history books and biographies…

Heinlein's "Stranger in a Strange Land" and "Time Enough for Love" are somewhat scandalous, but I thoroughly enjoyed them. Outside science fiction: P.G.

    They're both good. I'd definitely read Pragmatic before Complete, and I wouldn't feel bad for not finishing Complete. Outside the box, I'd recommend Heinlein's Time Enough For Love, for the attitude. Be as self reliant as possible, be as skillful as possible, be as useful to your team as possible. Find or grow an excellent team.

    The nice thing about Heinlein is he has a book for all stages. As I've gotten older I really prefer his "Time Enough for Love" novel, which is about looking back on a long life.

    …was broken. # Benjamin Franklin's autobiography showed me a history that was made of people, a people no different than me and mine, and that success comes from standing up and going your own way. # "Time Enough for Love" by Robert Heinlein taught me that, while culture is arbitrary and we should be free to try to make it what we wish, that doesn't make it fake or ignorable. # "Sherlock Holmes" by Sir Arthur Conan Doyle,…

    I also read Time Enough for Love every few years. I've owned and read and loved much of Heinlein's work over my life, but it's the one that's stuck with me for the past decade.

    …together — ." He croaked something in Martian and smiled. As an aside, I loved that book so much I went on to read every Robert Heinlein book. Some were disappointing, but I enjoyed most of them. Although, Time Enough for Love is probably my favorite sci-fi book, slightly ahead of with Stranger in a Strange Land.
