It's always too early to quit.
The most effective way to do it, is to do it.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Know or listen to those who know.
Again, it may be said, that to love justice and equality the people need no great effort of virtue it is sufficient that they love themselves.
The secret of freedom lies in educating people, whereas the secret of tyranny is in keeping them ignorant.
