Think about one of your idols. It’s EASY to agree with him/her, right?
But, can you disagree? Can you disagree with your idol?
Of course you can. And my case of study is Jim Rohn, but it can be your idol of life, it can be a friend, a relative, a friend of a friend, your boss, a guy on the TV or internet, or anyone that you have the luck of enjoying ALMOST a constant agreement.
