It's not about technology, it's about people. It's the realization that your job is to deliver value to someone, and then figure out how to (politely) get through your organization's red tape (and every organization has it) to get it done.
Coming back to technology - it's about simplicity. It's the realization your system is going to spend most of its life in operations and maintenance and you need to design systems that just work, work reliably, and when they inevitably have problems they're easy to diagnose and fix.
It's these skills that will take you to another level.
