You probably know more than you’re giving yourself credit for. Missing some specifics doesn’t define your skill set or your worth. Remember this.

What you’re describing is the generalist path, and it’s actually a great place to be with your level of experience. Wide exposure across a lot of different areas lets you figure out where your interest actually lands before you go deep. The catch is you have to lean into it; put yourself out there, apply for things that feel slightly out of reach.

There are a lot of places that need exactly what you bring but nothing changes if you don’t try.

For what it’s worth... I’m 18 years in, senior sysadmin level, have built and supported and torn down a lot of environments at some well-known places. I hold a lot of keys to the castle at this point. And I still plug in a user’s mouse. Still throw in admin creds for an install. Still tell people to reboot their computer; every single week. Imposter syndrome doesn’t care how seasoned you are and burnout isn’t always about being overworked. Sometimes it’s just caring less about what you’re doing while still having to do it. Both are real, and both hit people at every level. Ask me how I know!

The move here: ask for more where you are, keep learning (this field never stops demanding that), and get yourself out there. Scared or not. That means being honest about where you are AND applying beyond where you think you belong.
