I worked as a network engineer and got pretty frustrated working with outdated applications that were not user friendly. Once I became a supervisor, a large part of my job became writing and generating reports summarizing events that happened on the network that no one would ever read. I wanted to learn programming to automate the things I hated about my job.
I’m still an engineer, not a developer, but I enjoy writing user focused programs that reduce or eliminate worker frustration. As with many jobs, it’s not the networking that’s difficult, it’s all the other bullshit you have to do.
Also, learning how to parse, model and visualize data can really help you make your point to your management and get your ideas pushed through. Also a great way to earn brownie points with your bosses, as managers tend to love graphs.
Wish I could say it was a passion for me but I really learned out of necessity.
