Ok so I am 15 years old and Ive built close to 30 computers of which 5 are my own. Ive built computers for myself, friends, family, and even my school yet everytime I get the "are you sure you know what your doing", "what if you break something", "Im spending 1000 dollars on this should I trust you"..... Im sure you guys know what Im talking about. The thing is it always turns out fine infact in the last 2 days ive built 2 computers for 2 different friends. Though, admitely these people do stress me out a bit and make me feel like I actually dont know what I am doing. So my question is how do I get past this is there anything in particular you guys say or do to make them feel better. I usually say dont worry and show them a picture of my pc, but im not to sure of that tactic.
