I want to steal one out of Newton's book of physics and say "For every action there is an equal but opposite reaction." This is true when giving advice. For every negative advice, there is an equal but opposite positive advice. A negative advice is something that uses words like "don't" or "can't." Something positive does not have the word not anywhere in it.
The reason I am starting with establishing this basic rule is because negative forms of advice are not effective and may actually be counterproductive. What people tend to focus on is what tends to happen. So when we say "Don't drink and drive," it may be possible that just saying drink and drive in there will produce more drunk drivers. Rather, we should say the equal but opposite positive form "Ride Sober." This has a much more positive connotation to it and people are more likely to follow it's advice.
If you think about it for everything, you can always find the equal, but opposite form of advice.
"Anti-war" becomes "Pro-peace"
"No sexual harassment" becomes "respect others' space"
"No littering" becomes "Recycle/Throw your trash in the trash can"
These are just things that are present in culture. We focus on "no war" and "no sexual harassment," yet we live in a time where these have become more present and are becoming more present over the years. We need a peace campaign or a respect campaign.
This applies in personal applications as well.
"Don't raise your voice" becomes "Let's calm down and talk"
"Don't buy Pepsi" becomes "Buy Coke" (Coke is better)
"Don't lie to me" becomes "Be honest with me"
"Don't leave dirty dishes in the sink" becomes "Put the dishes in the dishwasher"
It is best to sit and think for a second about how you can spin it in a positive direction and use that form of advice. It is proven that people are more likely to do what you focus on (whether you tell them to do it or not). So focus on the opposite of what you don't want them to do. They are more likely to follow your advice.
