We all start somewhere, right? Allow me to suggest two good introductory titles by Bertrand Russell:
The Problems of Philosophy - Examines general terms and concepts.
The History of Western Philosophy - Analyzes notable thinkers from the pre-Socratic era to the mid-20th century.
A philosophical dictionary is also valuable (and fun to pore over), and unlike Wikipedia it's edited by a smaller number of peeps and so has a more cohesive and regular tone. I enjoy the one published by
Cambridge University Press.
Fair enough. If extemporaneous speech isn't your bag then read one or two of your school essays while standing before the camera and addressing it as if you were before a live audience (you might even scare up a few family members or friends so you aren't simply jabbering at yourself). That way we'll get an idea of how your gesticulations and other body language imply additional layers of meaning to your words.
