When someone look up to you to enhance their thinking, it is not proud moment but rather a privileged moment.
Not all do it. It is not because that it is not innate. It is because we fail to recognize them - guys who honestly want to improve their thinking. If we recognize, we add value to them and to ourselves.
And we have to believe (and it is truth too), improving others thinking is two way street. Don't think that you are only improving them. Their mere honest and commitment in fact enhances your thinking. So, enhancing the thinking can only be MUTUAL (it is NOT one-way street) - congregation of thinkers.
