Lu Zhou actually didn't have any extremely high ambitions.
He realized this about himself recently.
In the face of the universe, his influence was ultimately tiny.
He could spend months locking himself in his tiny room, trying to solve an equation or a conjecture by himself. However, for giant system engineering missions, he needed a team of scholars from many disciplines. It was no longer a solo-mission.
Even though he could design the ion thruster propulsion system perfectly, he couldn't build the propulsion system himself. He needed other people to help him.
If he wanted to have an impact on this world, he needed other people's help.
As an academic leader, his responsibilities went far beyond exploration and discovery. He was also responsible for guiding the next generation of scholars.
The more he pushed the boundaries of human knowledge, the more he realized how important it was to push human boundaries.
