In your speech to a group of highschool students you explain how you have seen people do stupid things at parties as a result of drinking. you've seen how drunk people put themselves at risk

" You have seen many people do stupid things at parties. The worst part is that they don't even know what they are doing. They think they are 'cool' by doing this urt they don't know how stupid they are making themselves look. Anything could happen to them. They will go into danger yet think it's okay. The most succesful people don't drive and drink, they don't do stupid things. So if you want to achieve your goals don't let this stop you.
