Education, especially when in depth is not always fun and it's not possible to always do it without sacrificing quality in my opinion. Education is boring at times but it's important and worth doing. I think, people should not always demand fun in everything, some things require efforts.
For example, in my current series, what exactly can I do to make it fun? I try to explain the reading in easy to understand manner with extra facts and concepts but that's all I can do. It's interesting but there seems to be no scope for fun on that topic.
