I believe people can learn most when they feel interested in what they will learn.

As everyone has their distinctive interests, I think we all have our own ways of learning. In class, I always try to do my best to conduct lessons which all of my students can find fun.

But as my students are very unique, I think they need self-study materials that are to their liking.

Please note that this textbook is for advanced learners =)
