How did you get started into Networking? What initial resources helped you the most?

Hello Everyone. As the two questions ask, how did you get into Networking and what are some good beginner resources that made you stay in Networking? Someone I work with said they are interested in Networking so I wanted to help them out as much as possible. Do you have any great online resource I can recommend to them? (other than this sub of course! :-) ).

His network skills are mostly come from setting up LAN parties, and basic client device troubleshooting (showing IP's and pinging devices).
