How does NFT listing work?

Could you elaborate on the process of listing a Non-Fungible Token (NFT)? I'm curious to understand the steps involved from start to finish. Do creators need to have a specific platform or marketplace in mind? Are there any prerequisites or requirements that must be met before an NFT can be listed? Additionally, how does the pricing mechanism work? Is it set by the creator or determined by the market? Finally, are there any common challenges or pitfalls that creators should be aware of when listing their NFTs? I'd appreciate a detailed explanation of the entire process.
