Mech pilots tended to do the stupidest things in the hopes of triggering their breakthroughs.
Those with fairly normal mentalities and modest ambitions would never think about resorting to extreme measures to step onto the path of godhood.
This was a perfectly sane and valid career choice. Mech pilots were only human, after all. They feared death and lusted for life. Why must they take excessive risks and push themselves so close to their limits when the chance of success was so abysmally low?
Mech pilots that clung to their sanity did indeed live longer than their less stable peers. They got what they wanted, but pretty much gave up their best opportunity to escape mediocrity.
Only the mech pilots that possessed the courage to challenge their limits possessed the qualifications to step onto the path of godhood.
