Unplottable, your approach is interesting. It's basically creating a workenvironment that supports what you should be doing on the computer. I know this works, except I'm probably too much of a computer geek so I would procrastinate for hours by trying to get everything in the Linux installation working properly.
(I currently run a dual boot WinXP/Ubuntu Linux box, as well as an OS X iBook at home).
Earlier this year I lost my internett connection for a couple of weeks, and in that time wrote a small computer game to teach myself a new programming language. From time to time I would have a few things I needed the web for, so I would take my laptop to a web cafe and do what I needed. My web use became very focused and effective. My computer use also became more focused, as the most interesting thing on the computer was the programing project I was working on.
Norbert, I've been trying to find my true purpose, but I'm not there yet. It's not easy for me, as I have too many options. I'll keep working on it though.
