What didn't kill you only made you stronger.
This was a quote that was generally used to help people who were going through a difficult phase in their lives. Giving them the hope that there would be a better tomorrow as long as they held on and muscled through the tough times. Survival was the key motive here.
This quote could also be used for people who had specific goals that they wished to reach in life. By giving up on many pleasures of life and accepting the suffering the path towards their goals entailed, they could obtain a better future for themselves. Hard work and suffering in return for a smooth sailing tomorrow.
It was truly a beautiful quote with an equally beautiful teaching. It was a quote that showed humans the essence of survival and the rewards of perseverance.
But Adam realized that this quote had to be changed for him, an ever-resurrecting immortal that he was.
