Are you familiar with Holstee and their awesome manifesto? I recently signed up for their (very affordable) membership to add to my mindfulness toolbox. Guess what? Their welcome kit includes developing your very own manifesto, identifying what you value most. I found this process enjoyable. The end result is below. A personal, mindful, value-filled declaration I'll reference regularly until its time to write a new one!
P.S. I put my face on it to, you know, claim it and hold myself accountable.
