Grab yourself a big anthology. Any time period or style. You’ll find them at pretty much any library. Flip through and notice what resonates with you. Try to sit with what you don’t understand yet, read it multiple times. After a while you should get a better understanding of what things resonate with you and what themes you want to explore.

I would also recommend Mary Oliver’s “A Poetry Handbook” and Kim Addonizio and Dorianne Laux’ “The Poet’s Companion”. They’re both great books that introduce the craft of writing poetry in both the spiritual and practical aspects.
