Book Reports / writing essay about the Great Gatsby and Hamlet [3]

hello ,
I have to write a well written essay tomorrow about those both plays and novel
I've read both of them but seems to have a problem on how to start
haven't right a thesis yet but I'm on it ,... but i guess i need some help with that also
i thought of comparing Daisy to Gertrude on how they both married brutish figures _ or maybe we should use another word _ and also how both worries about their status and wealthiness despite the things they know which is Daisy's love towards gatsby and gertrude confrontation from her son and yet didnt leave Claudious ,...

but i ought to have 3 body paragraph which means three arguments ,.. i only have one that i implied previously
thanks
