The end justifies the means.
The end makes all equal.
The eye is bigger than the belly.
The farthest way about is the nearest way home.
The finest diamond must be cut.
The fire is the test of gold, adversity of strong man.
The first step is the only difficulty.
The fox knew too much, that's how he lost his tail.
The fox preys farthest from home.
The frog in the well knows nothing of the great ocean.
The grass is greener on the other side.
