Excess of sorrow laughs, excess of joy weeps.

The road of excess leads to the palace of wisdom.

The road to excess leads to the palace of wisdom...for we never know what is enough until we know what is more than enough.

An excess of modesty is in fact an excess of pride, and more hurtful to the individual, and less advantageous to society, than the grossest and most unblushing vanity.

They are but beggars that can count their worth, but my true love is grown to such excess, I cannot sum up half my sum of wealth.

Excess on occasion is exhilarating. It prevents moderation from acquiring the deadening effect of a habit.
