Only the educated are free.
Know or listen to those who know.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
If you're going through hell, keep going.
The learner always begins by finding fault, but the scholar sees the positive merit in everything.
Mere goodness can achieve little against the power of nature.
Truth in philosophy means that concept and external reality correspond.
