Let’s start by defining the behavior you want to change.
It’s important to focus on a single concrete action, rather than the outcome you want to achieve or a broad category of behaviors. You are defining a specific behavior, not a policy.
For example, if you wanted to help people be healthier, it might be tempting to say ”get more exercise” or “tax sugary beverages.” But remember that we want a specific action that will help people be healthier. A behavior like ”take a 15-minute walk every day” is clear, concrete, and specific, so it would make a great key behavior.
With that example in mind, what’s your key behavior?
