Always desire to learn something useful.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
The dog that trots about finds a bone.
If you think you can do it, you can.
If you've got a talent, protect it.
You never know what motivates you.
I can, therefore I am.
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.
