Facepalm

It sucks to learn a lesson this way when they could have learned it by reading any of the paperwork that came with each component, or watching a video about it, or not ignoring all the various people who have already likely tried to explain it in person.

At worst, the slowest of those methods of learning the lesson would have been an hour or less of their time. This way is gonna cost hundreds or thousands of hours. And worse, could have cost forever, or someone else's forever, or multiple.
