The mind is the organ of possibility in a world of challenge.

四勿：“非礼勿视，非礼勿听，非礼勿言，非礼勿动。”四端：“恻隐之心，仁之端也；羞恶之心，义之端也；辞让之心，礼之端也；是非之心，智之端也。”颜渊的“四勿”，要牢记心里；下工夫闲静存诚，克服外部的干扰以修养心性；孟子的“四端”，要尽力扩充，下工夫格物致知，由近及远，推己及人。

Hatred destroys only the hater.

I don't have time to hate people who hate me because I'm too busy loving people who love me.

Nothing is more precious than independence and freedom.

保持冷静，但要关心。
