My job is stable and pays decently, but I haven't picked up a new skill in over a year. I keep waiting for a reason to leave that feels urgent enough. Has anyone left a job that's comfortable but stagnant?

I'm a junior engineer, but I inherited a project mid-construction because the designer left. I wasn't around for the early phases, but now I’m running the site meetings. I'm stressed about the technical gap and being asked questions I don't know the answers to. I don't want to appear clueless in front of the clients, even though I am. Is it okay to say that I don't know, but I will get back to them? Or does that look unprofessional?

What was the biggest mistake you made early in your career that ended up teaching you a valuable lesson? One of mine was assuming everyone interpreted requirements the same way I did. Learning to ask clarifying questions saved me from a lot of rework. What’s yours?

If you could permanently eliminate one workplace meeting from your calendar, which type would it be and why? I’d probably choose status meetings where everyone simply reads updates that could have been sent in an email. Curious what everyone else would remove.

A senior engineer on my team is leaving, and our manager sent a link for a farewell gift card. She mentored me when I was a junior, so I want to chip in, but I can't see what others are giving and have never done this before. She makes great money if that matters. The default options are $20, $30, and $50. What's standard here? Is $30 enough, or should I go higher since she helped me so much?
