The notion of work-life balance is often a set up to resent work and feel defeated. Life is work, work is life. Freud said the beacon of sound mental health is being able to work and love. Work is part of life. Find meaning in it and have boundaries to feel empowered in your life and in your work.
Boundaries are essential in relationships and make them sustainable. If you can respect and care for yourself by way of boundaries, it opens a space to truly care for others in a much more profound and unburdened way.
