Intelligence and freedom of thought
Intelligence is just the practice of thinking freely about something, (without accepting any kind of external dogma as a-priori true.) Nobody can ever teach you to be intelligent.
99 percent of being intelligent is realizing that all those fucktards who give you advice like “Don’t marry” or “Go study this and that” are just fucktards who don’t have anything better to do and are using you as a means to raise their self esteem m by having people listening to them.
Most people recognize some of these people as fucktards, but few recognize and are able to break free from all of them.
