I 32F sometimes regret choosing my current career, what should I do?

I'm currently working as a senior data analyst. I'm good at it, get good performance reviews, and make a good income doing it. But I'm not passionate about it.<br><br>I earn good income. I'm grateful for what I have and I can't imagine going back to making lower income, and all the struggles that come with that. However, I also feel like I have been doing the same thing and living the same life for many years. I've lost count of how many years I've spent in this career.<br><br>I sometimes wish for more passion in my career, but no other careers I've researched excites me. I want to switch but I don't know what I want to switch to. I also don't know how realistic it is for me to switch career at this point of my life when I'm in my mid 30's. I am stuck.<br><br>What should I do about it?
