Everything is done by CONTRACT. It DOESN'T matter whether it's Civil or Criminal. There is NO LAW anymore because there is NO MONEY (Of substance) and since there is NO LAW and since there is NO MONEY everything is done by CONTRACT, it's AGREEMENT OF THE PARTIES. So remember, that theoretically anything that is done COMMERCIALLY in the CIVIL WORLD by any kind of “accounts”, its BASED ON A SIGNATURE.

Jack Smith

A lot of things in life seem impossible until it's done. Don't be afraid to attempt the impossible.

Rita Zahara

Impossible is not a fact... it's an opinion. What's impossible only remains so until someone finds a way to do what others are sure can't be done.

Tony Robbins

Theoretically, I grant you, there is no possibility of error in necessary reasoning. But to speak thus "theoretically," is to uselanguage in a Pickwickian sense. In practice, and in fact, mathematics is not exempt from that liability to error that affects everything that man does.

Charles Sanders Peirce

If the objective of testing were to prove that a program is free of bugs, then not only would testing be practically impossible, but it would also be theoretically impossible.

Boris Beizer

It is always impossible until it is done.

Nelson Mandela

It always seems impossible until it's done.

It always seems impossible until its done.

Nelson Mandela

It only seems impossible until it's done.

Because of the Turing completeness theory, everything one Turing-complete language can do can theoretically be done by another Turing-complete language, but at a different cost. You can do everything in assembler, but no one wants to program in assembler anymore.
