It is extremely hard, because we are constantly looking for an easier and better solution then the one that is given to us. Sure some instructions are simple like keep quiet and sit still. However you do get those instructions where there are ambiguous meanings and innuendos that could make you misunderstand things. The instructions that we are given are guidelines and also vary when it comes to importance. You can choose to follow them and commit your total understanding towards instructions or you could just leave them as ambiguous and not follow them at all. The choice is yours!
