I need to write 3 thesis statements for Memoirs of A Geisha about the general themes. I need one for friendship and betrayal, fate and destiny, and suffering and strength.

Thesis writing can be a daunting thing to do. Teachers will stress over and over again just how important it is to have a solid thesis statement for a paper. Those teachers are correct. The thesis statement guides the entire paper. It is the foundation.
With that said, writing a thesis can be quite formulaic. The first thing to remember is that a good thesis statement makes an argument. It is not a statement of fact, because then there would be nothing to prove. A second thing to remember is that a thesis needs to be specific, yet it also needs to give you room to write, discuss, and use various forms of support. For this reason, I recommend using a double-sided thesis statement. Start the thesis with the word "although." This will force you to make a statement that the second half of the sentence attempts to discredit. Because the thesis statement is set up with two opposing views, your paper is free to explore both of those particular angles while pushing your reader to believe your main, second argument. This format of a double-sided thesis statement also fits well with the general writing prompt providing you with three sets of opposites. A possible thesis statement might go something like the following statement:

Although Chiyo suffers greatly at the hands of various characters, it is this suffering that allows her to become one of the strongest characters in the novel.
