Almost everyone of us are very good preachers . The very easiest thing in this world is offering unsolicited advices to others. But, when it comes to practicing sum of the offered ones. Our mind would say "NO no it is for others not for me " I can break the rule.
Take Dale Carnegie's case he had two divores in his life but he wrote a book "How to stop worrying and start living". Whatever he couldn't practice in his own private life he had just preached it to others. ATleast, he had translated his ideal thoughts into a courseware for billions of people.
