Recruiting a newcomer can be easy but building him as a great member is challenging.

Well said friend 🤗
My personal experience is Some newcomers come to Steemit with money in mind. After posting two or three articles, When they do not get what they want, they leave Steemit.
So a newcomer must have a good patience and a recruiter also need to teach them that there is more to Steemit than just making money🤗
