How do you deal with impossible to please customers?

Sometimes, I have a customer who is so picky and demanding and even when I do my best work, they are not satisfied. And, I know it's not my fault as other customers are perfectly happy with the same results. How do you deal with impossible to please customers?

Ask the client up front what they want and get all instructions in writing before you start work. Then, later if the client says they wanted something different, you have proof otherwise.

Once you gain enough credibility and good reputation, you won't have to deal with difficult customers anymore and will be able to afford to hand pick which customers you work with.

Handpick?? How? You can't choose who places an order with you here.

Not every freelancer works on seocheckout. And, for those who do, you can always reject an order if it is coming from a difficult to please buyer (such as someone you have worked with before and know will cause trouble). In this way you can choose whom you work with.

You could always raise your prices and that will allow you more money for your work. This could also provide you with a better class of buyers who are not so picky.
