Great question here.
My answer: why does it need to be exciting for you to do it?
Boring things that reliably work are awesome for business. Literally the holy grail.

The idea that you need to be "excited" by something to work on it is a broken, bad idea.
It's one of the MOST common failure modes of many talented indie hackers and creators I see.
The antidote is simple: professionalism. More here:
Hobbies and side projects are great for excitement because you can put them down with little to no consequences when you get bored.
If you find yourself instinctively putting down your BUSINESS when you're bored it might not be a businesses. It might be a hobby.
I've wandered a bit from my original point about repetition, but the main lesson is this:
If you're afraid of repeating yourself - because it's boring or because you think people will call you out on it or something else - interrogate that.
And see if your fear matches reality.
