Did you know that ....if you have a speech assignment you should actually take some time and get yourself prepared for it. Sometimes if you dont do this you will find that you are down to the last minute and you have no idea what to give a speech on.

This may or may not work for you, but in certain situations it may be your only chance of getting a passing grade on the aforementioned speech project. Someone may or may not come up with a good idea and be able to help you.
