This is my favorite quote by Henry Ford.   I do not like to ever say or think I can’t.  It is giving up.  I will say I won't, but not that I can't.  Life is a matter of choice and I usually like to pick my battles and save my energy for those things that are really important to me. When a battle is picked, I believe that I will be successful.  The question is what is important enough to expend valuable energy on and just do it.
