Lives of the Noble Grecians and Romans or Parallel Lives is a series of biographies of famous men, arranged in tandem to illuminate their common moral virtues or failings, probably written at the beginning of the second century AD by Plutarch. Parallel Lives comprises 23 pairs of biographies, each pair consisting of one Greek and one Roman, as well as four unpaired, single lives. It is a work of considerable importance, not only as a source of information about the individuals described, but also about the times in which they lived. Volume I contains 13 pairs of biographies from Theseus and Romulus to Cimon and Lucullus, with comparisons.
For now, though, I really enjoyed Plutarch's Parallel Lives. He compares the life of an ancient Greek and Roman - EG Alexander vs Caesar.
2) Axler's book on linear algebra. That's when I started to think in terms of vectors as more than the typical "magnitude and direction" concept you are used to in UG physics. It took many years, but I'm finally beginning to apply this to more advanced topics.
3) Concurrency in Action, by Anthony Williams. The training in multithreading aside, that motivated a deeper interest in things like how caches worked or atomics for someone without a CS background like myself. I haven't finished Three Easy Pieces yet, to my eternal shame as I read this thread, but that might also be added on this list by the time I'm complete.
4) On the right-hemisphere side of the brain, books such as Christopher Clark's "Sleepwalkers", Jonathan Smele's treatment of the Russian Civil War, and Richard Thornton's "Odd Man Out" on the Korean War have been useful in teaching me to dig deeper than the standard narrative when looking at history. I'm looking forward to Christopher Goscha's book on Dien Bien Phu and James Howard-Johnston's recent drop on the great final war of classical antiquity in the 7th Century, in a similar vein: both are out, just haven't gotten the chance to digest them yet. Also, Plutarch's Parallel Lives. They aren't "history" in the sense that we know it, but they do teach you that, yes, the lives of famous ancient figures do have lessons that can and should apply to you.
Hell to the fuck yeah, when you get to Plato, you have to want it. I still haven't made it through the Republic.
Plutarch Parallel Lives has a lot of really good biographies. Pick any. Hell, pick Life of Antony.
Herodotus is fun but junk. Thucydides is tough but meaty. Switching to the Romans, Tacitus Agricola is awesome.
Read Gorgias Encomium of Helen (short), I think he's the only Sophist we have, and you might think Plato was a little tough on him.
He gives a biography of one famous Roman and one famous Greek and compares them.
If you enjoy history and literature, maybe Plutarch's parallel lives of Alcibiades and Coriolanus; or Christopher Lasch's "Culture of Narcissism" could provide some perspective. And as someone said below, Dale Carnegie's book on winning friends and influencing people, 100 years later, is a really useful, life changing book.
