I didn't originally plan on writing a second part but this didn't make sense as part of the first post, so here it is.
I think there's more to creativity and innovation than inspiration. Some times (though not always) inspiration is what comes easily.
It's the things that come after - the work, the persuasion, the rework, the second ideas, the pivots - that may prove to be hard. You need additional creativity to work through these things and you also need humility and resilience.
If you're feeling like your current position or career doesn't provide you with the opportunity to be creative, that may be true. It also may be that you're going through a different phase - one that is about building up something, in this case you still need creativity, but you need other things to.
