Mech design was a very demanding profession.
Mech designers had to be rational. They had to be capable of absorbing and applying an enormous amount of scientific knowledge.
Mech designers also had to be passionate. Those without feeling were no better than auto-designers that were incapable of designing groundbreaking mechs!
As Patricia explained, mech designers had to straddle the line between these two extremes and find a position where they could maximize their success.
Patricia was very suited to become a rational mech designer due to her excellent ability to control herself. Ves never saw her exhibit any strong emotion.
He met quite a few mech designers who impressed him with their level of control. Now that he thought about it, Master Olson truly came across as someone who was in absolute control of herself!
