Learning is paradoxical in nature. It can sometimes appear to be very simple. All of us are learning all the time, after all, from the myriad experiences we encounter in our daily lives. Learning is so simple that we rarely question its presence: it is as natural to our existence as eating and drinking. Yet, when we encounter difficulties in learning something, we no longer take the learning process for granted. Learning can suddenly seem very difficult indeed. I remember trying numerous ways of learning Latin declensions at school until it suddenly struck me I could make a nursery rhyme of them: lupus, lupe, lupum, lupi, lupi, lupo. This revelation worked so well, I still have this (useless) knowledge down pat even now.
