sister who complained that her sons were always asking for money but never replied to her letters.
So Carnegie bet her £100 that he could get them to reply within a week.
So he sat down and wrote to each of his nephews asking how they were. He ended both letters by saying that he was enclosing £50 for each of them.
He received a letter back from each within the week giving Carnegie their news and ending with a “PS. Uncle Andrew, you forgot to enclose the £50.”
Carnegie was successful because he used his brain - and as Christians we need to do the same.
