I can't think of a single instance of learning a subject that mattered where I would describe as "having fun". Let alone too much fun.
Only on games which are fun themselves I could describe them as a fun experience, but they don't really require deep learning. The ones that do, will often stop being fun too.
It's very easy to enjoy the first stages of learning and have fun with it, but to really learn something, you have to get past that phase. Then it's much more about repetition and grit, than it is about fun.

So, for me, too much fun == not really learning.
