When writing a thesis statement, you always want to describe what you are going to be writing about, not simply what the essay is about. You never want to write "This essay", "My paper", etc as your thesis statement. Your reader knows that they're reading an essay, they're the ones that choose to read it!
If you are writing three body paragraphs, you want to include your three arguments or statements that you will be discussing in those body paragraphs. For example, you could write: "Volunteering at an animal shelter helps animals by feeding, spaying, and finding new homes for neglected pets." In your paragraphs you would then discuss things like how much it costs to feed so many animals, how a shelter runs, how a vet must come and neuter the animals, and how other people can help by adopting shelter pets. You are able to be imaginative with this, it's just your thesis statement that is a guild for what you are writing about. Some people will leave writing their thesis last once they have written their other parts to their essay since it helps them not to be held down by their thesis. Usually a thesis will have to be written and rewritten several times to get it just right.
it means you are your own person, with your own brains. The way you perceive things, nobody else can. They way you draw, build, play, dance and live may not be very good, but it is your own way, that nobody else can do
