You can Google all day in advance of a meeting and come across like the most intellectual and up-to-date person on the planet. You can go to church every week and carry a bible around and pretend to be right with God. You can suppress your true feelings and carry on all day ‘acting’ as if everything were cool and most people would think you are emotionally at the top of your game.
