Without self analysis and critical examination, one cannot be honest. Honesty is a very expensive piece of information.

Ask any wealthy person to give you the price for honesty…tell them you want truth at any cost. Watch their faces; listen to the tone of their voices. You will observe a certain degree of discomfort in their reaction.
Truth is annoying and that is why we had the hacking scandal via News of The World earlier this year. The owners of News of The World kept denying. Denial is the best weapon for avoiding the truth.
