Hi. I'm Geoff. Other kids used to babysit for petty cash.
I fixed Macs in dental offices.

From age 18-25, I was, by trade, an:

Apple Certified Tier 1 Tech Support Kid
Apple Support Professional (10.4 - 10.8)

Apple Certified Guy Who Can Actually Fix It
Apple Certified Technical Coordinator (10.5 - 10.8)

Apple Certified Someone Who Knows Open Directory
Apple Certified System Administrator (10.5 - 10.6)

Apple Certified Screw Turner
Apple Certified Macintosh Technician (rolling/ongoing)

But I burnt myself out on this stuff.

I've retired from consulting to retrain as a programmer.
Apparently, I enjoy sniping bounties on apple.stackexchange.com for fun in my spare tme.
