My 2 contemporary and 2 classical monologues and notes of each - pick 6-10

Before choosing my monologues I need to make sure they are a reasonable time, and make sure all my monologues have a clear objective. I want to make sure they all have a distinct beginning and end. 

I want to choose around 6 monologues:

- 2 Contemporary - one dramatic - one comedic
- 2 Classical         - one dramatic - one comedic 

And four others that I feel I could add a lot more to and feel I could perform to my standard.
