"It's the challenge and satisfaction you receive from keeping your environment up, running, and healthy. The best systems admin is the one you never see. Anyone that knows the business, should know what I mean. I also like the opportunity to learn new things and integrate where necessary like using GLADE, Python and eclipse to develop a GUI for an application that was command line only. Small app, but I had a blast learning. It was a front end for the Dev team at OTS and they loved it."
