newbie questions

I am an absolute newbie to Active Directory and System administration
in general. I have read Active Directory 2nd edition by O Reilly. Can
anybody please give some ideas for a total starter? Should I read more
or should I start experimenting? I am going through group archives
which is helping me a lot.

Also, are there any specific points a newbie should be aware of?

Your help and time would be highly appreciated.

Thanks a lot.
