That would be a great stride in the belief factor. Possible it would help him yet, an affirmation opposite to what one already believe and know does not always work.

However asking what if... what if it works, what if it is possible for me the mind would look to see what one would need to do to find out what if. It will also look for other things that it has learned in the past.

What if I can...

Opens the door to at least giving it a go with an open mind and allows the skeptic to suspend skepticism enough to try it with an open mind. It also releases you from the emotional entanglement of fear of failure. It is also the opposite of What if I cannot.

Can means able to. When you are saying "I can" you saying, "I am able to".

When you say cannot.. When yo say "I cannot:. You are saying, "I am able to not"

Whether you can or cannot is a choice you make when others have demonstrated that it is within the realm of possiblity.
