It means that if you don't make good use of every day and don't spend it well, you have failed your life.

This sentence comes from the famous German philosopher Friedrich Wilhelm Nietzsche's Zarathustra.

The original text is,

Every day without dancing is a disappointment to life. A person who knows what he lives for can endure any kind of life. In fact, people are the same as trees. The more they yearn for the sunshine in the high places, the more their roots will extend to the dark underground.
