I'm quiet because I prefer listening over speaking unless I'm comfortable with the people and enthused about the topic. I'm enthusiastically geeky. I love to make things (food things, crafty things, techy things, you name it).
The people I'm close to.
Space to myself (can be small).
Space not full of people (must be large).
Assuming I have to survive in this current world, technology (laptop, internet, etc.)
