A clear idea starts with a clear prompt.

Decide what you want to achieve before writing a prompt. One clear objective makes a result easier to evaluate than a long instruction that asks for several unrelated things.

Explain your audience, where the content will be used and the format you need. A brand campaign and a personal celebration video call for different contexts.

Treat the first output as a starting point. Note what works, add missing details and test a few approaches against the same goal.
