Meaning:

You use this proverb to say that you are wasting your time if you keep delaying something that must be done instead of doing it today. Edward Young (1683–1765), a British poet, was the first one who said this.

If someone says, "Procrastination is the thief of time," he/she advises you not to procrastinate (put off doing something that you must do) and use your precious time wisely.

Example:

Don't put off the things you must do today. Procrastination is the thief of time.
