The essence of this topic is not to discourage anyone from doing the right thing especially the newbies but just to advise them on some certain things which they have failed to understand.
What you said could be likened to a story I heard about a particular man who has been jobless for many years and have been relying on the charity of others to survive, wrote a book titled "How to create wealth and be financially independent." He approached his neighbour and asked him to buy the book and the neighbour replied him to go read the book he wrote first. It's funny sometimes when I see posts or topics of some newbies dishing out advice on a particular subject when they have zero knowledge about it. The truth is you cannot give what you don't have. I'm not trying to belittle anyone or saying that all newbies are the same because merit or ranking cannot be a yardstick to judge how knowledgeable one is, but some of them should not be hasty, rather take some time to read and learn.
