Learning is not being taught; it is not the simple transfer of knowledge from a teacher to a pupil. It is certainly not doing hard and boring homework set by the teacher.
Learning begins when your brain does what it does best for a living: noticing, observing and remembering what interests you. It goes on when you spot a desirable goal and start to move towards it: quite independently, you set yourself intermediate aims; directing yourself, you select the means of acquisition and choose your study habits; you autonomously devote of your time, and engage with the resources to hand.
However, it works better if you are not alone, if you have a companion, a mind-coach, by your side; someone to help you fulfil the task in hand by reminding you to recall all the useful appropriate stuff that you already know, and encouraging, daring you to put it into practice.
