Be honest about whether something is learning or entertainment. Real learning is extremely hard and effortful. (Podcasts, Atlantic articles, pop science books, anything that’s a bit too digestible is more “entertainment” than real learning)
Environment matters a lot; move to where you flourish maximally. Put yourself in environments where you have to perform to your utmost; if you can get by being average, you probably will. (Greek saying: “A captain only shows during a storm.”)
