This lesson was originally designed for high school seniors in a college and career class. The lesson was given to me by a retired professor who wrote a book on success in college.
However, the information is valuable for any high school level, in particular, grades 10-13 and also college freshmen. You can tweak it however you need to and decide to use only parts of it.
A PPT is included that provides the personality types but it is also in a doc.
