I feel like I've stopped growing in my current role, but I'm comfortable where I am. How do you know when it's really time to move on?

I've been at the same job for a while now, and nothing is really wrong. It pays okay, the people are nice, and I know what I'm doing. It's comfortable.

But I also feel like I'm just... stuck.

I don't really learn anything new anymore. Most days are just the same thing over and over, and I catch myself wondering if this is all there's going to be. At the same time, leaving feels like a risk because I don't actually hate my job.

I keep going back and forth. Is this just what happens once you've been somewhere long enough? Or is this the point where people start looking for something new?

I guess I'm worried that if I stay, I'll regret wasting a few more years. But I'm also worried that I'll leave a stable job for something that's not actually any better.

Has anyone else been in this situation? What finally made you realize it was time to move on?
