The problem with your friend may not be just plain laziness but three other areas. He may be suffering from
1. Fear of Failure or
2. Fear of Rejection.
Try and find a book written by Brian Tracy on these 2 topics. He taught this in his Phoenix Seminar.
3. Another reason maybe he is burnt out from overwork or worries or worse, he is suffering from depression.
Of course there are also many other areas to cover like no desire, no dreams and goals so the needs are not there. Maybe he doesn't like MLM or be his own boss. Likes a simple life etc. The message I want to send you is laziness may not be the problem. Also please do not try and push MLM down the throat of your prospects.
