Is that a movie ? <| sep |> Wait , really ? <| sep |> reverymanshouldknow is great for skills and street smarts and there are many informative posts to be found there ! rlifeprotips is another good one along the same lines . As far as politicshistoryecomonics etc . , I have found that rather than try to find a place to learn all the basics , try to adopt a curious attitude toward these subjects . For example , if I come across an article about an event in history that I know nothing about , I could skim through it and let it slip from my memory or I could dig deeper into areas of the article that I don ' t understand . I look at the brain like a muscle you can get by with the minimal amount of information but if you want to grow , you have to push yourself farther than the surface level stuff . You may not remember every detail but the concepts and main facts will stick with you and can be applied to the next event you come across .
