This one is strangely motivating, quickly became one of my favourite video game quotes. From Pokémon X/Y's Elite Four Siebold.
"You see, cooking is the type of art that disappears as soon as it is completed. Pokémon battles are the same. Even memories of sweet victory soon fade after the battle ends. To devote yourself entirely to such a life, made up of fleeting experiences--that is truly artful."
Gets better with what he says after battle: "Devote yourself entirely, so even that which will fade and disappear is ingrained forever upon your heart and mind!"
