I've read this 10 times blunt by now but I can't blunt understand blunt this at all blunt.
A thing which I reckon every single person on earth should be told relatively young, as in, pull an eighteen year old aside for a private conversation and tell them: smart people are not immune to bullshit. In fact, smart people are often more susceptible to bullshit, especially their own bullshit, because smart people are better at rationalizing it and sliding it past their own common sense and better judgement.
