Anna's philosophy
Anna is not a Unix guru – there's a world of things she doesn't know! But she knows enough to be considered expert-ish 
. And her knowledge has been hard-won, making many mistakes – even now!
Mistakes are not bad – they're your friend! One of Anna's favorite sayings is:
- Good judgement comes from experience
- Unfortunately, experience comes from bad judgement!
- So go out and start making your first 10,000 mistakes!
Anna's philosophy for teaching Unix is not just to show you how to do thing, but to explain how things work and why. This understanding will greatly help you when you're troubleshooting your own (many!) mistakes. So put on your thinking caps!
