Balancing work and study is a challenging thing to do, especially for university students. Prioritizing well-being becomes crucial for personal growth amid these competing demands. Effective time management and quality sleep are vital for maintaining well-being, yet they often prove challenging for working students due to time constraints and sleep deprivation. This study seeks to explore how time management and sleep quality impact the well-being of working students. Using a non-experimental correlational quantitative research design, convenience sampling was employed, involving 251 students from various universities across Indonesia. The findings reveal a significant p-value (0.000 < 0.05), indicating that well-being is influenced by time management and sleep quality. The calculated R-squared suggests that approximately 50.2% of the variability in well-being can be explained by these factors. Notably, effective time management and superior sleep quality predict heightened well-being, with higher levels of both corresponding to increased overall well-being among working students.
