How do you get the excitement back if you're on a long streak?

So I've been using Duolingo long enough that it's become background noise: think I'm on a 780-some streak at this point.

I'm essentially only dropping by daily to do one lesson and maintain the streak, as opposed to actually wanting to learn something new. It's probably not helped by the new unit structure constantly repeating things that have just been covered; I think this is the fourth time I've worked through the weekdays in Hindi...

Which is all to ask: for those lemmites (lemmings?) who are on a long streak, how do you get the passion back?
