Who best knows the right balance of life for oneself?

The individual self is the best source for knowing the right balance of life because each person's circumstances, preferences, values, and goals are unique. This self-awareness allows individuals to assess what truly matters to them and how to allocate their time and energy accordingly.

While friends and family can provide valuable insights and support, they may not fully understand an individual's aspirations and challenges. Similarly, experts and professionals can offer guidance based on general principles or studies, but they cannot tailor advice to the specific nuances of a person's life. Colleagues can share experiences and suggestions, yet their perspectives may be influenced by different priorities or work-life balances.

Ultimately, personal reflection, self-assessment, and experience play a crucial role in determining one’s own balance, making the individual self the most authoritative voice in this matter.
