If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
Wherever you are - be all there.
Well done is better than well said.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
Never complain and never explain.
If you think you can do it, you can.
The human imagination has already come to conceive the possibility of recreating human society.
The product of the scientific imagination is a new vision of relations - like that of artistic imagination.
