Cicero’s Six Mistakes of Man
- The delusion that individual advancement is made by crushing others
- The tendency to worry about things that cannot be changed or corrected
- Insisting that a thing is impossible because we cannot accomplish it
- Refusing to set aside trivial preferences
- Neglecting development and refinement of the mind and not acquiring the habit of reading and studying
- Attempting to compel other persons to believe and live as we do.
