Ask How do you deal with a project that keeps growing bigger than what was originally discussed?

[Edward22]

Sometimes a project starts small and simple, but as time goes on, the client keeps adding more tasks and ideas. Before you know it, the work becomes much bigger than what you first agreed on. This can affect your time, energy, and even other jobs you planned. How do you handle this kind of situation in a polite way, and how do you bring the discussion back to the original agreement without causing tension?
