nothing is impossible

Do you know all that there is nothing in this world that we can not do.

all we can do. It all depends on our own point of view - each.

something we will be unable to do because we are ordering our own brains to not do it.

A concrete example of this suggestion:

a swimming athlete who has shortcomings (incomplete body parts) can swim freestyleafter practicing all these years. He can do it because he always ordered his thoughts to be able to perform activities that, in the unyielding accompanied his efforts.
