Why is it so hard to sell an NFT?

I've been trying to offload an NFT for quite some time now, but it seems like an uphill task. Could you possibly explain why it's so challenging to sell an NFT? I've heard of the novelty and potential of NFTs, but my personal experience has been quite different. Is it the lack of liquidity in the market? Or is it the high volatility that makes potential buyers hesitant? Perhaps the pricing strategy needs to be more nuanced? Or are there specific platforms that are more conducive for selling NFTs? I'm genuinely curious about the intricacies and would appreciate your insights.
