You must eat to live, not live to eat – A famous line attributed to socrates

If you want to make a big impact during a talk at a conference and you want that to be remembered by people, then choose to have a chiasmus. It is said that every presidential candidate of USA goes through the rigour of choosing the right chiasmus that will help them win.
