英文小作文：

Apropos of the topic of success, I believe that success is a combination of effort, perseverance, and opportunity. Success requires that we put forth effort towards our goals, even when faced with obstacles and challenges. It requires perseverance to keep going when things get tough, and it requires opportunity to be able to take advantage of the right opportunities at the right time. However, success is not solely determined by external factors, but also by our own attitude and determination. We must believe in ourselves and have the courage to pursue our goals, no matter what obstacles lie ahead. In conclusion, success is a journey, not a destination, and it requires effort, perseverance, and opportunity to make it happen.
