英文小作文：

Success is not solely dependent on our own efforts, but also on the support of others. We need to be able to rely on the people around us to help us achieve our goals, but we also need to be able to support them in return. When we are dependent on others for everything, it can be difficult to maintain our own independence and self-confidence, but it can also be a valuable experience that teaches us to rely on ourselves more than we ever thought possible. In the end, success is about balance and cooperation, and it is only through working together that we can achieve our goals and dreams.
