.... people just get nervous about there time and $$$ investment....
Yes sir, I'd be lying if I said "I'm not nervous"! With hours spent sweating in my garage, sweating in my mind, hoping that the machine shop did everything correct to my block and part of the assembly work, multiple times working on my engine while my anal pucker factor was way too high, not doing everything I should have, having some unexpected parts unavailable, and then going over-budget... Yeah... I AM nervous about making sure I'm doing everything "right"!!!... and especially firing my engine.
