Great idea, Rena. Standing on your head is a great way to gain a new perspective. Do not make it the main focus of the essay, though. Make it one of the topic paragraphs, and you can also make it your theme. But end the first para with a sentence that tells a main idea that is about perspective, not standing on your head.
It is a great theme!!
Chose the philosophy you feel is prevalent in America
This essay is not about sports, KathyLala. It is about what seems prevalent in America. So what do Americans value -- sportsmanship or winning?
Use examples, such as performance enhancing drugs, games won with poor sportsmanship, and so forth. This is about psychology, not sports.
Anyway, next time you have a question please start a new thread. You can link people to it if you want to, but start a new thread.
