What is the best way to fire a toxic, high-paying client?

[Btaliat]

Working with clients that are very toxic sometimes can give the clients some types of headache. That's why it is always better for a freelancers to know how to discard clients. You don't need to be harsh with them. You only need to be polite before deciding not to work with them again. You may make an excuse telling them that your business models is changing and you may not be able to meet up with their demands again.
