Kitty Katty has it summed up pretty well there.
Think of a time in your life, at school perhaps, with a subject you felt that you were rubbish at, but other people seemed to manage fairly easily. Think how you felt going to each lesson, how you dreaded getting homework back. Your self-esteem was pretty shot at - how was your learning?

So then think of something you really enjoyed - not enough lessons in this subject for you - they were good, the work came easily and you enjoyed the challenge - perhaps you pretended not to, 'cos your friend didn't like it, your self-esteem was way up! How was your learning?
