I wouldn't go as far as to say it was my best decision in my career, however it was an important one. I've noticed how I've gone from "click-friendly" GUI's and window managers like Gnome/KDE to Fluxbox, turned syntax highlighting off and at the same time increased my productivity/effectiveness. At first I missed the "fanciness", the new felt boring and pale, however as time passed it made me realize that I'm now focusing on the important things and I'm in control. So yes okay, it's one of my best decisions.
