This quote means that time is precious, and wasting it can be seen as a sign that the person does not realize the importance of living a meaningful life. We only have a limited amount of time on earth, so it is important to make the most of it and use it wisely. Taking the time to do things that are worthwhile, such as spending time with family and friends, learning new skills, or exploring new places, can help bring joy and purpose to life. Wasting an hour of time is an indication that someone has not grasped the value of life and how precious limited time can be.
