I am continuing with this series after a long time. And, honestly, when I think, the lessons or the entire series sound condescending to me! It might project out an image as if I know things better than you and that it makes me in a position to advise you.
Plus, it gives a very wrong notion of your personality. Dragging your feet literally means you are careless and you have no motto in life. Or, it can also put your forward as a sickly person. And, that is definitely what you do not want to project, irrespective of the truth!
