The six mistakes of man

Cicero, the famous Roman philosopher and statesman, wrote this over 2,000 years ago.

The six mistakes of man:
1. The delusion that personal gain 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 cannot 
accomplish it.

4. Refusal to set aside trivial preferences.

5. Neglecting development and refinement of the mind, and 
not acquiring the habit of reading or studying.

6. Attempting to compel others to believe and live as we do.
