Cerentha Harris has a great idea for creating a distraction-free desktop:
It’s all too easy to get distracted from work on the computer. But there’s a simple technique to help regain focus: create a new User account, one specifically designed for getting work done. That means creating a desktop stripped of extraneous bookmarks, applications, music and movie files, plug-ins, extensions…unless they’re designed for task management or your work related projects. Think of this desktop as your work persona. Creating a dedicated account for work related tasks is like having a work outfit compared to the comfy-cozy sweatpants of leisurely online time.
I keep my desktop pretty distraction-free at all times, but this is an awesome strategy, and one that I would recommend to my non-minimalist friends. Check the full post for step-by-step instructions.
