Honesty is the first chapter in the book of wisdom.
~ Thomas Jefferson
By three methods we may learn wisdom:
First, by reflection, which is noblest;
Second, by imitation, which is easiest; and
Third, by experience, which is the bitterest.
The only true wisdom is in knowing you know nothing.
Wisdom ceases to be wisdom
when it becomes too proud to weep,
too grave to laugh,
and too selfish to seek other than itself.
~ Khalil Gibran
