I must say some people are so stubborn or lazy that they hardly take the pain of reading the instructions before using anything. Those people are too conceited to accept that they can't do things without any help or guidelines. But, some painstaking workers bother to read those guidelines that some people skip and do the things right like the first time.
I pity those who miserably fail again and again. But yes, at least they try without any help. So, I thank them for giving a try even as without them, my this article's fodder wouldn't have been fed completely.
