Even if you come out with something creative, must find a way to stand out among millions of other similar items? How?

There are some paid methods and some free ones like Irene Zhao's to get potential buyers. Either spend money or time to get traffic to your NFTs. Most of the successful sellers have their own websites to showcase their NFTs. Then people can buy from a link  from their website to Opensea or whatever platform they use to mint your NFTs.

Found one website where you can list your drops to their collectors. Think got to pay. Haven't tried: https://nftcalendar.io/

But your NFTs must be unique and have an interesting history or story line. Just minting beautiful photos won't cut it. You need to promote them and get the word out. Not so easy.
