I’ve written fairly extensively about learning on this site. Learning is something so essential and foundational to our success in society yet the majority of us were never really given the skills or habits to learn effectively. Instead of being taught ideas like active recall, interleaved practice, or spaced repetition, we were taught to highlight books, reread chapters, and take notes. While the latter things do have their time and place in a learning environment, they are not what makes for truly effective learning. In infographic present below does a nice job of display some good and bad study habits. Check out the infographic below and I will write more about the issue of learning how to learn at a later time.
