My friends and I were into computers before this, but four of us got into systems administration and network architecture primarily from dumpster diving around the SF bay area in high school. Sun Microsystems and SGI workstations, Cisco networking equipment, IBM and DEC servers... we got good getting enterprise and/or obscure technology working and talking to each other which gave us a more generalist or fundamental knowledge of systems and troubleshooting. And it was so much fun...
