I need a simple topic for a 2-3 minute unprepared speech, preferably personal and requiring no external research. Any suggestions?

I recommend:

• 4. My favourite place of rest.

This topic allows you to speak from personal experience, describing a place you know well, why it brings you peace, and what you do there. It's easy to generate content for 2-3 minutes without needing to recall facts or construct intricate arguments.
