Although this is a personal question that only you can answer, we can still provide an example that will serve as inspiration for your writing.
I will use the topic sentence "sports are necessary for a good education."
As an avid soccer player and a student with a thirst of knowledge, I believe that sports are absolutely necessary for students to have a good education. This is because there are many advantages to sports in a school setting. First, sports allow students to move around and exercise. This is particularly important nowadays, when many people have extremely sedentary lifestyles. Second, sports allow our body to release endorphines, making us feel happy and therefore more receptive to learning. Finally, sports allow us to work on our team-building and bonding skills, which are valuable skills in an education context. In conclusion, sports are an essential component of a well-rounded education.
