At 15 I set my heart on learning; At 30 I firmly took my stand; At 40 I had no delusions; At 50 I knew the Mandate of Heaven; At 60 my ear was attuned; At 70 I followed my heart's desire without overstepping the boundaries of right.
A good man does not make a warrior, just as good steel does not go for nails.
If you devote your life to seeking revenge, first dig two graves.
Learn as if you were not reaching your goal and as though you were scared of missing it
What the wise seek is in themselves
There are 1,000 lessons in defeat. But only one in victory.
