@james.thinks1: Fluid intelligence is the raw part. It is how fast you work out something you have never seen before. It is the thing every other kind of thinking sits on top of, and it moves. Three is doing what you are bad at, because easy repetition changes nothing. Two is consistency, which beats intensity every time the question gets studied. One is refusing to hand the hard part of a problem to something else. The grappling IS the exercise. Comment learn and I'll send it to you. #fluidintelligence #cognitivescience #learnsomethingnew #StudyTips #selfeducation #brainhealth #criticalthinking
