Love everyday of it, though it can be frustating at times (but what job isn't). I went to college for 2 years for Computer Networking. Then worked for 1 year at a Mom & Pop computer repair store. The job opened up the year I graduated college and I applied but didn't hear back. Then it opened up again the next year, I applied again and got the job. I am A+ certified and almost Microsoft Certified (needed like 2 or 3 more questions right to be certified). I haven't had to go back and take the test again though because I was hired (I was planning on it though).
Mostly I deal with I-D-10-T errors....LoL (that is id10t or idiot). I have to know networking though as that is probably the second biggest thing I do.
