Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
Do not weep do not wax indignant. Understand.
Only the educated are free.
You never know what motivates you.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Know or listen to those who know.
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.
