Hachiman Hikigaya — memorable quote from Yahari Ore no Seishun Love Come wa Machigatteiru.

“The words of your past are fundamentally unrelated to who you are now.”

“The truth is everyone is going to hurt you, you just got to find the ones worth suffering for.”

“Women tend to kill when it's not necessary. They kill for reasons of passion. For trivial reasons like love and hate.”

“A romance won't keep itself going forever. Eventually, you lose that all-important spark. Love has to be nurtured if it's going to last. If you want to be with someone forever, you need to put effort into the relationship... Great, now I'm talking cliches.”

“Clausewitz, he pointed out that no matter how carefully one plans, on the battlefield, even the smallest of details can cause setbacks. Regardless of how well-thought it is, armchair strategizing only works in the realm of theory. Unexpected troubles, or uncontrollable factors such as weather. Operations face those sorts of troubles. They are the cause of strife on the battlefield.”
