Love & fight.
愛せ、戦え。
Kindness and compassion can be quite addictive.
It’s quite comfortable when someone is kind and/or compassionate to us. Then we tend to forget to keep sharpening our edge: hard-work, perseverance, or toughness.
Not everyone on this planet is our ally. We have tons of haters and naysayers in our life, and we’ve got to fight. We always need someone who is kind and compassionate to us, but never forget to prepare for battle.
