Any man can make mistakes,

but only an idiot persists in

his error.

The truth will set you free, but 

first it will make you miserable.

If you cannot change your mind

then you aren’t using it.

When you have faults, do not fear to

abandon them.

The trouble with most of us is

that we'd rather be ruined by

praise than saved by 

criticism.

More people would

learn from their mistakes

if they were not so busy

denying them.

All men make mistakes, but a good 

man yields when he knows his

course is wrong, and repairs the

evil. The only crime is pride.

Think lightly of yourself and

deeply of the world.

Those who cannot

change their minds

cannot change anything.

Stupid is the man

who always remains 

the same.
