understand yourself in order to better understanding others.
知己方能解人。
if you doubt yourself，then indeed you stand on shaky11 ground.
如果你怀疑自己，那么你的立足点确实不稳固了。
if you would go up high，then use your own legs!do not let yourselves carried aloft;do not seat yourselves on other people’s backs and heads.
如果你想走到高处，就要使用自己的两条腿!不要让别人把你抬到高处;不要坐在别人的背上和头上。
