Aphorism Pairs

I don’t recall who listed several complementary pairs of aphorisms. I will list two pairs here before I forget.
Look before you leap. He who hesitates is lost.
What goes up must come down. On what principle is it, that when we see nothing but improvement behind us, we are to expect nothing but deterioration before us. (Macaulay)
