Horizon of expectation

Horizon of expectation is the idea that when you make a plan, you make it based on what you expect to happen in the future. This means that if you're making a plan to do something like save money, you would think about what the future looks like for you and plan based on that. For example, if you expect to get a raise in the next year, you would plan your budget with that in mind. If something unexpected happens in the future, like you don't get a raise, you would have to adjust your plan.
