I could do exploration in this particular career field, and it was a goal that, even if I didn't reach it, it was so high it seemed almost impossible, but even if I didn't reach it, I would still have a good time and a very satisfying career.

Now you're coming back to Earth, and things are getting more and more dynamic.
