Busyness can lead to burnout and exhaustion by causing us to constantly be in a state of stress and overexertion. This can lead to physical and mental fatigue, as well as decreased productivity and creativity. Over time, this can have a negative impact on our mental health, leading to anxiety, depression, and other mood disorders. To protect our mental health, we must prioritize self-care and rest, and learn to say no to commitments that may lead to overextending ourselves.
