Some guiding principles:
Timing:
Draft a script or comic-style storyboard that is short but impactful. Use conversational language. Keep your sentences concise and to-the-point.
Jot down some ideas, sound effects, or facts that you think would make a good beginning.
What does the listener need to know about an issue affecting the community, or an organization that is working on that issue? Describe the music, sound effects, and/or real human dialogue that would help convey the message.
Is there an original or copyright-free jingle, sound effect, or point you could make near the end of your PSA to help it resonate?
