Plenty of us have come across the above meme, or a version of it, especially over the past 18 months. Self-care is so important. What do you do for self-care? Take a walk? Stretch? Bathe? Meditate? Consider writing about that.
Alternatively, you can take the idea of the cup itself, literally and/or metaphorically. What do you do to 'fill up your cup'? What empties it? Or maybe you have a favourite cup that you drink from now, or remember a favourite cup from childhood (shout-out to the plastic Tommee Tippee sippy cup with ducks on it from my childhood that my son still drinks from now at his grandparents' house!).
