How do I stop scope creep without sounding deeply aggressive?

[Btaliat]

Scope creep is common in freelancing. Most clients take advantage of the new freelancers and they ask them to provide them scope creep. It is better the freelancers know how to notice scope creep and find ways of rejecting them. You may tell your clients politely that you will collect money for any excess tasks separately. Doing this will make it easier for the clients not to give you extra work because they know you will charge for it.
