I have been a computer repair technician for about 10 years. I repair and maintain computers and servers. 
Cool, is it a tough job?
Yes, i have to configure new hardware, create new computer networks, and updating software.
I am not good at computers, did you have any training?
Yes, I had to go to a professional institution to get a certificate to prepare me for the job. It included classroom work and on the job teaching.
Wow. Sounds like a lot of work. Did you enjoy the classroom work?
Yes, but I enjoyed the apprenticeship even more. I got to learn my trade on actual jobs.
