Every adversity, every failure, and every heartache, carries with it the
Seed of an equivalent or greater benefit.  Al Gore, Sr.

Flatter me, and I may not believe you. Criticize me, and I may not like
you. Ignore me, and I may not forgive you. Encourage me, and I may not forget you.   William Arthur

History has demonstrated that the most notable winners usually
encountered heartbreaking obstacles before they triumphed. They won because they refused to become discouraged by their defeats. Bertie C. Forbes

Unsuccessful people are always asking, 'What's in it for me?'
Brian Tracy
