hi Lili, welcome aboard!
I'm also new to Steemit, and figuring out what to post does seem daunting at first, I think because of the money tied to it. but treating it like any ol' personal blog is probably the right idea.
[also, to fit the 'Lili'-naming scheme, what about "PoLilishing It Up!" ...wait, no, that's not nearly as good as I thought it'd be haha]
have fun on steemit, and good luck!
