How do I handle a client who wants me to sign a Non-Compete?

There is a situation where freelancers will be asked by the clients not to work for any other person again except the client only. Freelancers need to be careful while signing this. In fact, they need to review for now long and the money to be paid before agreeing to such an agreement. Not doing this may make the agreement not helping the freelancers at the end . It is even better for freelancers to reject the agreement. What do you think about this?
