The gift of fantasy has meant more to me than my talent for absorbing positive knowledge.
A person who never made a mistake never tried anything new.
Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.
The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it.
We cannot solve our problems with the same thinking we used when we created them.
Anyone who has never made a mistake has never tried anything new.
The true sign of intelligence is not knowledge but imagination.
