wow sounds good!
I've been basically computer technician for couple years some time ago, now I do different job in same company though :)
my long-term experience and advice is, most valuable technicians are those who can communicate with people (speech, phone, email), and troubleshoot stuff calm and efficiently (not lazy or slow though!) on their own, being able to search solution yourself, so try to do so ;)
And I mean as a computer technician working at the back. I don't have to deal with customers. I basically build computers, troubleshoot software, clean computers and probably even do some networking. Even though i don't really know how. I'll learn though
