Always desire to learn something useful.
Without hard work, nothing grows but weeds.
Never complain and never explain.
The wise does at once what the fool does at last.
Who seeks shall find.
Be gentle to all and stern with yourself.
It's always too early to quit.
Only the educated are free.
After a storm comes a calm.
The dog that trots about finds a bone.
Though I had success in my research both when I was mad and when I was not, eventually I felt that my work would be better respected if I thought and acted like a 'normal' person.
