A prompt is a specification
Role, context, task and format, plus an example, fix most bland answers.
Generic output is usually a specification failure, not a model failure. A prompt that works names who the model should act as, what it needs to know, the one task, and what the answer should look like.
Examples do the most work. If you want a certain tone, paste one piece you like and say "match this". It beats a paragraph of adjectives. Save the prompts that work, and where you can find them in three seconds.

Learn it in the course, copy it from a playbook, see it work in a case study.
