MS Students begin the year with the Discovery Module, "What is Character?"
This question may be the cousin of What is Life? No one knows for sure. While the answer might be unattainable, its pursuit can be worthwhile. There is an endless reservoir of quotes on the subject, many of them anonymous: “Character is what you do when no one is watching.” “Character, not circumstance, makes the person.” - Booker T. Washington “Character is revealed when pressure is applied.”
Hopefully, the Discovery Process will lead you to a definition that works for you. This module is offered as a start.
