Has anyone landed the perfect job, yet still felt unfulfilled?

I (28F) recently started a new job at the beginning of September. The job was a step up the career ladder AND it’s for a very large, pretty cool company. Everyone I have met has been wonderful, the culture is incredible, etc. I am very lucky to be here.

The thing is…I just can’t seem to feel excited or motivated. I used to be extremely career ambitious and climbed the ladder very quickly throughout my 20s. However, I started losing the ambition I’ve had over the last few years and I can’t seem to get it back…some of the reasons including being burnt out on corporate greed/corporate politics, seeing the insane layoffs lately, including to top performers (I get it, business is business, but I’m struggling to fully engage knowing I could one day be at the other end of a layoff) etc. I’ve developed a “what’s the point” mentality.

Has anyone been in a similar situation? How have you gotten your spark back? I’m really upset at myself for landing in the perfect career situation, yet struggling to feel fully driven and engaged.
