WOW, one thing you need to understand and make it your philosophy. If you believe in him he will believe in himself. If you give up on him he will give up on himself. This is true no matter who he is and what his potential and abilities are. This is true for parents, mechanchim and Rebbeim. Those who who walk through the life of a child have an obligation to that child and that is to believe in him and to be a great role model for him. One needs to understand that as a role model for each and every child we have the power to either “make them or break them”.
So if YOU believe him to be lazy he will be lazy. If you believe he can accomplish he will eventually accomplish. Never give up on him or his potential. I am currently reading a book on Rebbetzin Kanievsky, I am getting tremendous chizuk from her. I only had the zchus to meet her twice in person, but her smile and her unique ability to care for each and every person she meets and benches carries with that person for a very long time. She will be with me forever in my heart. The book about her life gives me tremendous insight and chizuk. I believe you can, and anyone can learn many lessons from her.
