Only the educated are free.
Be kind whenever possible. It is always possible.
If you think you can do it, you can.
I can, therefore I am.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
The dog that trots about finds a bone.
Expect problems and eat them for breakfast.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
The best way to have a good idea is to have a lot of ideas.
Satisfaction of one's curiosity is one of the greatest sources of happiness in life.
Facts are the air of scientists. Without them you can never fly.
