Forget the negative, never forget the positive.
悪いことは忘れ、良いことは覚えておこう。
Forget a bad day, but never forget that you always have so much to be positive about.
Forget what made you feel bad, but never forget what made you smile.
Forget what hurt you, but never forget what it taught you.
Forget the bad things, and never forget the good things. Always distinguish these two—that’s the key to have a better life.
