Self-care is crucial. It is critical for your mental and physical health. And it is critical for stress management.
Audre Lorde, the "black, lesbian, mother, warrior, poet" wrote: "Caring for myself is not self-indulgence, it is self-preservation, and that is an act of political warfare." Yes, you read that correctly. Self-care is political. Self-care is not self-indulgent. Self-care is necessary.
