The difference between Impossible and Improbable

[Lorenzo]

“The impossible often has a kind of integrity which the merely improbable lacks.”

~Douglas Adams

[A Layman]

Impossible is what makes a man who couln't make it.
Improbable is what takes a man who couldn't think of it.

To overcome man's anxiety on achieving things beyond imaginations, the best thing he has to do is to forget...forget that you are what you are...or take away all your egos, the I am or Im then everything will be alright.
