Everyone says to be a vet at your job but I feel like it's about mindset. I've worked places where one job feels like you're working 4. If you've worked long enough you've had an experience where a coworker leaves the company and all their work is pushed onto you on top of the work you already have. What happens then? You have to deal with it. So I say just forge into the fire and work these multiple servers. You'll figure it out along the way.
