A man must have a certain amount of intelligent ignorance to get anywhere.

It is man's destiny to ponder on the riddle of existence and, as a byproduct of his wonderment, to create a new life on this earth.

It is the 'follow through' that makes the great difference between ultimate success and failure, because it is so easy to stop.

One fails forward toward success.

It doesn't matter if you try and try and try again, and fail. It does matter if you try and fail, and fail to try again.

You will never stub your toe standing still. The faster you go, the more chance there is of stubbing your toe, but the more chance you have of getting somewhere.

Our imagination is the only limit to what we can hope to have in the future.
