Hey greenhills, your essay is decent, though there are a few issues that I found when reading it. For example you should focus on one specific topic/argument. For example you say:
"When something or somebody is overrated", you follow by saying "much is being expected from them. You start by giving two examples "something" and "somebody" and in the same sentence you revert back to "them" as in the "somebody". You should stick to the "somebody" rather than adding too much. You can certainly make your point with just one rather than two.
