This isn't a bad thing, a disadvantage, a failing, or an oversight; the ability to grind it out, the ability to get it done when you don't feel like doing it, is a skill and a really useful skill at that.
It's a total fallacy, some sort of made-up fairy tale, to imagine that the most important projects get done without people having to grind it out at some stage.
So settle down and deal with it.
It shouldn't be like that all the time, but it will be like it some of the time.
