Anyone who remotely knows me knows that I tend to organized, which is saying that the last Transformers film contains a few explosions. I'm actually pretty proud of my organizational abilities, they've helped me on the job and to keep my own life in order (especially good in these tough economic times). My very job, Project Manager, is based on me being good at planning.
Fandom is a good reason for this. My hobbies are a big part of how I developed these skills.
If you get involved in fannish activities, like any activity, you have to get organized. At worst you need to follow the plans of others – collaborate on the writing, show up for the game, etc. You may even take on larger projects and events, planning cons, writing fanfic epics, etc.
If you have successful fannish activities, you ARE organized.
