Effortless learning isn't learning. Real expertise needs the right kind of struggle: what cognitive scientists call “desirable difficulties.” Learn how to apply them.
I'd argue that some things can be difficult and fun at the same time, it depends on how you look at them. There are very difficult games I really enjoy playing, complex books I find lots of fun reading, or vocally demanding karaoke songs I love singing, etc. It's about catering to your level in my opinion. But indeed, the idea that learning "should always be fun" is misleading.
