英文小作文：

When it comes to success, we often focus on the outcome, but it"s our expectations that drive our efforts and actions. Expectancy is the belief that we will achieve a certain result if we take certain actions, and it can influence our motivation and behavior in numerous ways.

For example, if we have high expectations for ourselves, we are more likely to take action and persevere through setbacks, knowing that our efforts will eventually pay off. Conversely, if we have low expectations, we may give up easily or not take action at all, which can lead to missed opportunities and regrettable outcomes.

In business, expectancy can impact a company"s strategy and marketing efforts. For instance, if a company has high expectations for its products and services, it may invest more resources in research and development, create a more attractive marketing campaign, and strive for a higher level of customer satisfaction. Conversely, if the company has low expectations, it may not prioritize these aspects as much and may miss out on opportunities to grow and compete effectively in the market.

In conclusion, expectancy is an important factor that influences our motivation and behavior in numerous ways. High expectations can drive us to take action and persevere through setbacks, while low expectations can lead to missed opportunities and regrettable outcomes. Therefore, it"s important to have realistic expectations about our abilities and efforts, while also setting high goals and striving to achieve them.
