If you can dream it, you can do it.
If you think you can do it, you can.
Well done is better than well said.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
The most effective way to do it, is to do it.
Who seeks shall find.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
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.
