This phrase is a proverbial expression that means "Work hard and play even less, and a person will become dull and unenthusiastic." It is a humorous way of saying that when you have no time or energy for leisure activities, you will eventually become tired and lacking in interest.

In a broader sense, the phrase can also be interpreted as a metaphor for the importance of balance and variety in life. Just as too much of a good thing can be overbearing, too much work and play can be overwhelming. The phrase encourages people to find a healthy balance between productive work and enjoyable leisure activities, so that they can stay motivated, energized, and fulfilled.

In a more modern context, the phrase can also be used to caution against burnout and the dangers of overwork. It's a reminder that taking breaks and engaging in activities that bring joy and relaxation can help prevent exhaustion and maintain overall well-being.
