Well here's my unconventional take on it. It won't give you many tips but it might comfort a bit. We were already apex predators before our minds apparently went into overdrive. We were already using tools and hunting in groups better than anything else. The only thing likely to eat us was a lion, and only if desperate. So what were we competing against that applied an evolutionary pressure that selected so strongly for intelligence, theory of mind, etc. in a feedback loop? The best hypothesis I've encountered is -- other humans. Competing for social status. Competing for mates. Predicting the behaviour and allegiances of your political opponents. Keeping track of kin. Keeping track of networks of "I owe yous". Gossip. We've evolved to be as inscrutable and perplexing to other humans as possible, while also evolving a toolset to decode other people's intentions and thoughts. An evolutionary arms race, maybe. tl;dr: Humans are the most complex system other humans encounter and have to understand, by a mile. We all fail at it to varying degrees.
