Either you run the day or the day runs you.
Always desire to learn something useful.
The dog that trots about finds a bone.
Wherever you are - be all there.
Well done is better than well said.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Begin to be now what you will be hereafter.
By failing to prepare, you are preparing to fail.
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.
