What is deepest in you is deepest in others. Write from that.
I love this quote: “the whole energy which expresses itself in the galaxies is intimate. It is not something to which you are a stranger, but it is that with which you, whatever that is, are intimately bound up. That in your seeing, your hearing, your talking, your thinking, your moving, you express that which it is that moves the sun and other stars.”
-- I find it aligns with my way of thinking/ an ideal way of looking at life, my inner-universe, and cosmology. I heartily agree that writing to satisfy our authentic selves is more likely to resonate deeply with readers than trying to pander to the masses.
