persuasive speech ideas?
so I am taking a college business and professionals speech class, and our next assignment is to do a persuasive speech. but she doesn't want it to be about legalizing everything, abortion, death penalty anything like that, since everyone seems to want to do things like that. she said for us to "think outside the box" like why people should use car signals or why we should drink more water, simple things like that. but I for the life of me cannot figure anything out. so anybody have any ideas?
