I can't really object to the OP statement, true or not, if it makes people think maybe, its doing some good in that alone.
Gary O, (my forum hero of course), has come up with more sayings by the lady in questions, ones we'd all probably agree with and even admire!
When you hear sayings like "Cometh the hour, cometh the man", that suggests an element of chance in whoever gets brought to the top in whatever field of human enterprise, or leadership roles, so I guess there maybe isn't a formula for success all can follow.
My old boss became very successful, yes by hard work, yes by real brains or intellect, yes by being business savvy, but when asked to give lectures on what made for good man management, or what was the secret, he said, "There is no secret",(that must have grabbed the attention of those listening expecting to hear some formula for success!).
However, he did say of himself too, that he felt his job entailed, " Rubbing dull pennies", as in making dullards like myself shine a little brighter, and in this way he helped bring the best out of us, (.., echoes of Mary Kay Ash's statements I think in his words too).
