"Having regrets about past actions is extremely counterproductive. Uhm... how should I say it.... Oh, yeah! Every action we take is the correct one from our point of view. Even though... looking back we can say that a certain choice was the bad one, we are saying that while being in a completely different situation from the one we were in back then." Oh, I'm quoting one of my teachers from Kusari... welp...
"Dwelling on past actions just dilutes your present; or... at least, that is what I believe. We should all learn from our past actions, but we should not let them take over our present."
"By the way.... Delta was always like that. You could even call it a "drama magnet". For some weird reason, people like to mess with everything/everyone that is present in that System" he starts eating again.
