No fault of your own. If you don’t get that repetition, you don’t get as good at it. That goes along with the thought of “its quicker and cheaper to throw parts at it” mentality. I was the on site tech for 20 years and had 3 or 4 side accounts of my onw. When you work for a small or mom and pop shop, you don’t have the luxury of throwing 5k worth of parts at something.
