Much damage is done because people do things because they seem, at the time, like the right things to do. Only afterwards do they say, 'Oh, I never really thought about those particular consequences for my actions.' Yet sometime, we can over-think. We can mull over a matter until we have entirely shrouded our minds in mist. So, how can you tell if you are now paying too much attention to an important matter - or not enough? Well, if you are worried or confused, it is too much. You should know the rules of game called life, you should apply rules and play well to win.
