Know or listen to those who know.
Things do not happen. Things are made to happen.
Do not weep do not wax indignant. Understand.
Only the educated are free.
If you're going through hell, keep going.
The dog that trots about finds a bone.
I can, therefore I am.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
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.
