Accuracy of statement is one of the first elements of truth; inaccuracy is a near kin to falsehood.

Brevity

Never be so brief as to become obscure.

Credulity

Credulity is belief in slight evidence, with no evidence, or against evidence.

Enthusiasm

To waken interest and kindle enthusiasm is the sure way to teach easily and successfully.

Habit

Any act often repeated soon forms a habit; and habit allowed, steady gains in strength, At first it may be but as a spider's web, easily broken through, but if not resisted it soon binds us with chains of steel.

Self-improvement

People never improve unless they look to some standard or example higher or better than themselves.
