Yes. I am the dumbass doing the widebody thing, in steel, by hand. I walk out to the garage, survey the wreckage, an ask myself- "WHY are we doing this again?"

But, I pick up my tools, and the next thing you know, three hours have gone by. I then step back and say- "I did this", and depending on the result, I either sit down and admire, or shut the lights off and slink away.
