Six from Cicero

These are six priceless facts proclaimed by Cicero, who lived between 106 BC and 43 BC, and was a Roman politician and lawyer, who served as consul in the year 63 BC. He came from a wealthy municipal family of the Roman equestrian order, and is considered one of Rome's greatest orators and prose stylists. These facts are true today as they were over 2000 years ago:
1. The delusion that individual advancement is made by crushing others.
2. The tendency to worry about things that cannot be changed or corrected.
3. Insisting that a thing is impossible because we ourselves cannot do it.
4. Refusing to set aside trivial differences.
5. Neglecting development and refinement of the mind, and not acquiring the habit of reading and studying.
6. Attempting to compel others to believe and live as we do.
