Ask HN: I ask for the link of an article of personal development published on HN

Can you give me the URL of a HN article, published between March and January (both inclusive), bound to an article written by a spy that explained how to get people to like you and influence them please? (A spy or someone working in the secret service of a country) I think I remember one of the things he advised was to make people feel like they were making a choice.
