If you intend on having a career as a freelance writer then one thing that you should bear in mind at all times is how to keep your client happy. A freelancer's clients are his/her bread and butter and so it pays to give these important people exactly what they want.

When you are offered a brief or you bid for a job make quite sure that you understand the client's instructions and follow them as closely as possible. It is ok to make suggestions that might improve the piece of writing that you have been given to do but only do this with the client's agreement. If you learn how to keep your clients happy then you will be a happier and less hungry freelancer.
