You never know what motivates you.
Always desire to learn something useful.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
Never complain and never explain.
Begin to be now what you will be hereafter.
Who seeks shall find.
Things do not happen. Things are made to happen.
Leap, and the net will appear.
It's always too early to quit.
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.
